11 pairs of costars that you'd be surprised to learn were actually classmates

The two actors, who are a few months apart in age, attended New York City's LaGuardia High School of Music & Art and Performing Arts.

In a 2017 Instagram post, Elgort said that he and the "Call Me by Your Name" star "played on the same basketball team, we had the same drama teacher Mr. Shifman, we had the same science teacher Mr. Singh," and got nominated for Golden Globe awards in the same year: Elgort for his role in "Baby Driver" and Chalamet for his part in "CMBYN."

Elgort also told MTV that "no one disliked Timmy" in high school.

Mendes, who became a breakout star for her role as Veronica Lodge on the hit CW show, said that she used to see him and twin brother Dylan Sprouse on campus.

She also told Office magazine that she met Cole "on certain occasions" but he doesn't remember at all.

"I saw him around and there was a time when we had class in the same building so I would always see him outside," she said. "He was a weirdo! He had really long hair down to his butt cheeks. He was really shy too. I would see him at parties sometimes and I always kind of randomly talked to his brother, but I never got a chance to talk to him because he was more to himself."

Even before Winston was a student at Yale, Nyong'o was assigned to show him around the campus. They remained friends throughout college as part of the school's drama program and even went to see the first "Avengers" movie together, long before landing their Marvel roles as M'Baku and Nakia.

"He was extremely tall, and he has quite the presence — but he was also very internal and pensive," Nyong'o told The Hollywood Reporter.

She added: "He was on edge because he was auditioning to get into the school, but he also had a very clear idea of who he wanted to be in the world."

After appearing in 2018's "Black Panther," Duke and Nyong'o teamed up again the following year for Jordan Peele's psychological thriller "Us."

The two actors, who are less than a year apart in age, both grew up in New York City.

During a podcast called "The Big Ticket With Marc Malkin," Wolff said that he and Hawke both dressed up as Power Rangers for Halloween one year.

When asked by Insider if there's one thing fans would be shocked to learn about "The Hills: New Beginnings," Port said: "I think one of the most surprising things is that Spencer and I actually go way back and went to middle school and high school together!"

The two stars were both born in 1993 and attended Los Angeles' Harvard-Westlake School. They told Vanity Fair that they met at a Bat Mitzvah and reconnected on their first day of high school.

"I have been basking in the glow of Beanie Feldstein since I was 14 years old," Platt said of the actress in a tribute for Variety. "We became instant best friends on the first day of freshman year, our shared seventh-period lunch setting us on a predestined path of lifelong love."

Platt and Feldstein will also star in a film adaptation of Stephen Sondheim's musical "Merrily We Roll Along," which will be filmed over the course of 20 years.

"I think what Ben and I have is beyond friendship, honestly," Feldstein told Broadway.com. "It's like a soulmate connection. We're like twins separated at birth or something."

McGillis starred as Charlie and Kilmer portrayed "Iceman" in the 1986 movie.

"I know Val from Juilliard," McGillis told Yahoo! Movies. "He was a year ahead of me."

Damon and Affleck met as kids and attended the Cambridge Rindge and Latin School in Massachusetts. They went on to play extras in the 1989 movie "Field of Dreams" and appear in movies like "Glory Daze" and "Chasing Amy."

The pair also cowrote the script for "Good Will Hunting," which earned them an Oscar for best original screenplay. In the movie, they starred as friends Will and Chuckie.

Damon and Affleck also costarred in the 1999 movie "Dogma." Next, they'll write the screenplay for a film called "The Last Duel," which they're also starring in.

During an appearance on "The Tonight Show Starring Jimmy Fallon," Gurira said that the "This Is Us" star is like "my big brother."

Gurira also said that she started attending NYU's Tisch School of the Arts shortly after Brown graduated, but he frequently visited the campus. They also almost ended up being roommates in Brooklyn, too.

"We didn't really know each other that well," Watson told Entertainment Weekly. "I remember… so little."

The actress went on to say that she mainly recalled seeing Brown "outside of school, ironically" in theater productions.

Similarly, Brown saw Watson in rehearsals for plays and praised her "incredibly beautiful and nuanced work."

He added: "I remember Sue before she even got to school was dating a guy in the class above my class. And so I'm all, 'Who's this little cute girl who Dre is going out with?' They're like, 'Yeah, that's Susan Kelechi Watson.' I was like, 'Oh. She's cool.'"

The two actors attended Newton South High School in Massachusetts together and graduated in 1997. Prior to that, they were on the same little league baseball team.

"John Krasinski and I have known each other our whole lives in the weirdest, most coincidental way," Novak told Ellen DeGeneres in 2014.
