The shocking real-life age differences between 34 fictional parents and their children

On "This Is Us," a show which jumps around multiple different time periods, Moore plays Rebecca Pearson, the matriarch of the Pearson clan and mother to Randall (Brown), Kate (Metz), and Kevin (Hartley).

And though Moore rocked impeccable old age makeup when she was seen in the current time, it's still funny to realize that she, at 38, is younger than 46-year-old Brown, 45-year-old Hartey, and 41-year-old Metz.

Her on-screen husband, Milo Ventimiglia, falls in the middle of his kids at 44.

Bonus: She's also younger than on-screen daughter-in-law Beth, played by a 40-year-old Susan Kelechi Watson and her son-in-law Toby, played by 41-year-old Chris Sullivan.

"This Is Us" wrapped up in 2022 after six seasons and pounds of old age makeup for all.

In "Succession," Cox plays Logan Roy, the aging patriarch of the Roy family and controversial owner of the global media empire, WayStar Royco. Ruck plays his oldest son, Connor, who doesn't seem to have an interest in the company at all.

However, Cox is 76, while his character is supposed to be least 80. Ruck, on the other hand, is 65, when his character is probably in his mid-to-late 50s.

Time travel and magical curses played a part here, so the characters are actually supposed to be around the same age — but it didn't make it any less comical whenever Morrison's character, Emma, would call Ginnifer's character, Snow (or Mary Margaret), "mom."

Emma's dad, played by Josh Dallas, is also only one year older than her.

While both look great for their ages — Cher is 76 and Streep is 73 — you can see from their recent red carpet photos how laughable it is that Cher would play Streep's mom. It's even more confusing when you remember the two played best friends and roommates in the 1983 film "Silkwood."

Jackson looks great for his age, but that still doesn't make casting a woman a whole five years younger than him make any more sense.

This isn't totally the fault of "Glass" — the actors originally appeared in the 2000 film "Unbreakable," in which Wood had to portray the mother of a young version of Elijah as well. She donned old age makeup in that film.

When "Mean Girls" was released in 2004, Poehler was 33 and McAdams was 26.

You'd be forgiven for forgetting about this movie — it was a critical and financial failure. Perhaps it had something to do with its ridiculous casting of Jolie and Farrell as mother and son, even though they're 11 months apart. They were also rumored to be dating.

Lorelai and Rory Gilmore have one of the most iconic mother-daughter relationships on TV — they're more like best friends than family. According to the storyline, Lorelai got pregnant as a teenager, and ran away from home to raise Rory on her own.

So it was true-to-life that the people at The WB cast Bledel and Graham, who are only 15 years apart. But a more glaring age gap was between Lorelai and Lane, Rory's best friend, who was supposed to be the same age as Rory. However, the actress playing Lane, Keiko Agena, is only six years younger than Graham.

Stefan was turned into an immortal vampire when he was 17, so casting anyone for that role would be difficult: Real people age. Wesley was already 27 when he was cast as Stefan in "The Vampire Diaries."

Stefan's mother, also a vampire, is played by Annie Wersching, who is only six years older than Wesley.

In real life, Ryder and Quinto look approximately the same age — which makes sense, because Ryder is only six years older than Quinto. However, during her brief appearance as Spock's mother in "Star Trek" she looked much older thanks to age makeup.

In reality, Ryder was 38 playing mother to a 32-year-old Quinto.

Bellisario was 24 when she was cast to play 16-year-old Spencer Hastings. Her mother, played by Fera, was 38 at the time.

Rutherford will turn 54 in 2022, and Lively is 19 years her junior at 34. In the show's canon, we know for a fact that Lily wasn't a teen mom — there was supposed to be an entire prequel show about her life in California as a teenager, with no mention of a pregnancy.

In "Riding in Cars with Boys," Barrymore plays Beverly Donofrio, who is 15 at the beginning of the movie (Barrymore was actually 26). The movie tracks Donofrio's life from her teens into adulthood.

However, her college-age son is played by Garcia, who is two years older than Barrymore — he was 28 playing an 18-year-old at the time.

Not many people realize that the film's protagonist, Ariel (played by Singer), is only 12 years younger than her movie dad, Reverend Moore (played by Lithgow).

"Blow," the 2001 film about real-life drug dealer George Jung, follows the Jung family for decades. Griffiths plays Depp's mother, despite him being five years her senior. During Jung's later years in the film, she even needs to wear age makeup to look the part.

The fact that the two are the same age works since Marty eventually travels back in time and meets his mother as a teen (also played by Thompson).

In order to achieve the older look, Thompson "sat through three-to-four hours of prosthetic applications a day."

Kelly was in her mid-20s when the show began.

Her infrequently seen mother Patti was played by McCommas, who only has a decade on her TV daughter.

Arthur was a year older than her TV mom, Getty — they were born in 1922 and 1923 respectively. It took 45 minutes to transform Getty, who was in her 60s for most of the show's run, into Sophia, who was regularly cited as an octogenarian.

Murray was 22 when the series began, while his TV mom Kelly was 34 — just 14 years older. However, it made sense since it was established that Karen (Kelly's character) got pregnant with Lucas in high school — though, she was supposed to be a senior, and therefore 17 or 18 years old.

"I'm looking at the script and it says I'm going to play the mother of Lea Michele, who, in real life is 25 years old," Menzel told "The Talk," "I was like,'This is not the best day of my life.'"

According to the New York Times, Lewis fudged his age and pretended to be 13 years older than he actually was because he was nervous he wouldn't get cast as Grandpa since he was younger than De Carlo.

Only later was it revealed that he was born in 1923, one year after De Carlo was born.

Sulkin played Chase, one of the titular runaways. Chase is a high schooler, but Sulkin himself was 28. His TV mom, played by Carradine was 46.

Lohman was almost 30 when she played teenager Katy in "Flicka" — her movie dad, played by country star-turned-actor McGraw, is only 13 years older than her.

Grammer was 38 years old when "Frasier" premiered in 1993. Mahoney, who played Frasier's father Martin, was 53.

Tom Selleck looks great for his age — he doesn't look anywhere near 77 — which is why this pairing works, despite the small age gap.

Cariou looks a bit more age-appropriate (he's 82), so it's semi-believable that the two are father and son.

The Stewart family on "Hannah Montana" is extremely spread out, age-wise. TV dad Cyrus is only 16 years older than TV son Earles, and Earles is 15 years older than TV sister Miley (even though they both play high schoolers). TV mom, played by Brooke Shields, is only 12 years older than Earles.

Nowhere in "Gossip Girl" canon does it imply that Rufus was a teen dad, making the believable 17-year gap between Settle and his TV son Badgley somewhat... less believable.

In fact, Lily (Serena's mom) and Rufus are said to have had a relationship before they had kids — and they were both out of high school when that happened.

The 24-year-old McKenzie was such an unconvincing teenager that the show eventually made fun of itself in an episode, in which McKenzie's character Ryan makes a comment about another young actor. "How does that guy play high school? Hollywood, man," he said.

Rowan was only 37 when the show premiered, making her just 12 years older than her adopted son, and only 14 years older than her character's biological son Seth, played by Adam Brody.

The first (or "original") Aunt Viv was played by Janet Hubert, who is only nine years older than Karyn Parsons, who played Viv's spoiled daughter Hilary. After Hubert controversially left the show after season three, the role of Viv was taken over by the older Daphne Maxwell Reid. But Reid is still only 18 years older than Parsons.

Sondra wasn't originally part of "The Cosby Show," but her character was included at the behest of Bill Cosby himself — he wanted to show that Cliff and Clair were successful parents, and had a daughter in college.

However, Rashad only had a decade on her eldest TV daughter — and Le Beauf is nine years older than the next oldest Huxtable child, Denise, played by Lisa Bonet.

Hale looks young for her age — she was still able to pass for a high school student at age 28, proven by her starring role in 2018 Netflix rom-com "Dude." But she's only 16 years younger than Combs, who played her mother Ella.

Gugino first appeared as a young woman during flashbacks in "Watchmen," and the choice was made to keep Gugino as Åkerman's mother for scenes taking place in the present as well, even though the two actresses only have a seven-year age difference. Her elderly appearance was achieved with facial prosthetics.

Leo is barely more than a decade older than Wahlberg, one of her sons in 2010 film "The Fighter." And she's just 14 years older than her other son in the movie, Christian Bale.

A time jump in season three made actors have to appear 20 years older. The villainous Laoghaire, played by Hudson, had two daughters during that time. One of her daughters, Marsali, is played by Lyle, who is only two years younger than her.

Lyle spoke to Elle about this strange age gap, saying, "Nell Hudson, who plays Laoghaire, my mother, she's like two years older than me! We're almost the same age, and she's my mom! The two of us were like, 'We look the same! That's so weird! How is this going to work?'"
