THEN AND NOW: The cast of 'Grease' 42 years later

Throughout the movie, he struggled to maintain his reputation as a cool guy and win over Sandy.

The same year that "Grease" was released, Travolta was nominated for his first Oscar for his role in the 1977 movie "Saturday Night Fever." He went on to earn another nomination for his starring role in Quentin Tarantino's 1994 hit "Pulp Fiction," which also starred Samuel L. Jackson.

Travolta starred alongside Kirstie Alley in the 1989 movie "Look Who's Talking" and its two sequels released in 1990 and 1993. He also won a Golden Globe for his role in the 1995 movie "Get Shorty."

Travolta has been married to actress Kelly Preston since 1991 and they have two children named Ella and Benjamin. Their eldest child, Jett, died in 2009 following a seizure.

She transformed into a more edgy look at the end of the movie, ditching her pastel clothing for an all-black skintight outfit with high heels and bright red lipstick.

She was already a Grammy winner when she starred in "Grease," having won her first award in 1973 and two more the following year. In 1982, she won the award for video of the year for "Olivia Physical."

Newton-John was also nominated for a Golden Globe for her role in "Grease."

In the years after "Grease," the singer released more than 10 albums, some of which were Christmas records.

She also collaborated with Travolta for the song "Take a Chance," which was part of the soundtrack for their 1983 movie "Two of a Kind." They reunited in 2012 for the joint holiday album "This Christmas." In 2019, Newton-John and Travolta participated in a "Grease" sing-along event and Q&A in Florida. They even wore outfits similar to those of their musical characters.

On the acting front, Newton-John starred in the 1980 movie "Xanadu," two holiday movies ("A Mom for Christmas" and "A Christmas Romance"), and 2017's "Sharknado 5: Global Swarming." She also guest-starred on season one of "Glee" and appeared as a guest judge on "RuPaul's Drag Race."

The "Physical" singer married "Xanadu" and "Grease 2" actor Matt Lattanzi in 1984 and welcomed a daughter named Chloe Lattanzi two years later. The couple divorced in 1995. Newton-John has been married to John Easterling since 2008.

Newton-John was diagnosed with breast cancer in 1992 and said that her treatment lasted for almost one year. It involved a "partial mastectomy, chemotherapy, and breast reconstruction" in addition to meditating and other wellness practices.

Her cancer returned in 2013, but the actress didn't reveal the news publicly. Four years later, Newton-John said that her breast cancer returned and it metastasized to her lower back.

In 2020 at a G'Day USA event in Beverly Hills, the actress told reporters that she was "winning over it well."

"I don't think about it a lot, to be honest," she said, according to People. "Denial is a really good thing and I'm getting stronger and better all the time! I'm doing well!"

Her health battle also led her to launch the Olivia Newton-John Cancer and Wellness Centre in Melbourne, Australia.

She thought that Sandy's image was too clean-cut for her to be part of the group.

She won her first Tony Award in 1985 for her role in "A Day in the Death of Joe Egg" and was later nominated for her parts in six plays.

Channing's role as Abbey Bartlet on the drama series "The West Wing" also led to several Emmy nominations. She's won three Emmys throughout her career for roles on "The West Wing," "The Matthew Shepard Story," and "Jack."

Channing also earned an Academy Award nomination for her role as Ouisa in the 1993 movie "Six Degrees of Separation."

After "Grease," the actress starred in two series: "Stockard Channing in Just Friends" and "The Stockard Channing Show." Channing followed with roles in films like "Practical Magic" and voiced Barbara Gordon on the animated series "Batman Beyond."

More recently, she appeared on the CBS series "The Good Wife" and Hulu's "Difficult People."

Channing has been married and divorced four times and has been in a relationship with a cinematographer named Daniel Gillham for decades.

He had an on-again, off-again relationship with Rizzo, who had a pregnancy scare during the movie.

The same year that "Grease" was released, Conaway made his debut as Bobby Wheeler on the sitcom "Taxi," which starred Danny DeVito and Christopher Lloyd. Conaway left the show during the fourth season and starred on series like "Wizards and Warriors," "Berrenger's," and "The Bold and the Beautiful."

Conaway also starred as Zack on the TV series "Babylon 5" and its accompanying movies.

The actor was married and divorced three times. He publicly struggled with substance abuse and detailed his issues on the reality TV show "Celebrity Rehab with Dr. Drew." Conaway also told Howard Stern that he attempted suicide several times.

Conaway was found unconscious in his home in 2011 and went into a coma. A representative for the actor told the New York Times that Conaway's back issues led to a dependence on pain killers. His cause of death was initially pneumonia and months later was ruled accidental. Autopsy results revealed that he died from multiple causes, Reuters reported.

Her bright clothing matched the vibrant colors that she dyed her hair. Frenchy is also the person who helped give Sandy a makeover.

Conn reprised her "Grease" role for the 1982 sequel that starred Michelle Pfeiffer.

In the '80s, Conn starred on the comedy "Benson," which lasted for seven seasons. She also guest-starred on shows like "The Jetsons" and "Cagney & Lacey."

The actress starred on the children's show "Shining Time Station" and later appeared as a nurse on a few episodes of "Law & Order: Special Victims Unit."

She split with her first husband, Frank Conn, the same year that "Grease" was released. She married David Shire in 1982.

He and Frenchy dated.

He appeared on shows like "Murder, She Wrote," "Beverly Hills, 90210," "ER," "Baywatch," "Even Stevens," and "House."

The actor also had minor roles in 2016's "Straight Outta Oz" musical and 2019's "The Silent Natural."

Pearl reunited with Conn for "Grease: Live!" portraying Mr. Weaver, a producer for Vince Fontaine's "National Bandstand." The two actors reunited with costars Travolta and Newton-John for a 40th-anniversary screening of "Grease" in 2018.

Rizzo confided in Marty after she missed her period and feared that she got pregnant. Seconds later, Marty spilled the secret to a bunch of people.

After "Grease," Manoff landed roles in TV movies and shows like "The Golden Girls" and "Murder, She Wrote." She also played Maggie Peterson in the 1988 horror movie "Child's Play."

You may also recognize the actress from her role as Carol Weston on the '80s and '90s sitcom "Empty Nest," which lasted for seven seasons.

In addition, Manoff won the 1980 Tony Award for best performance by an actress in a featured role in a play for "I Ought to Be in Pictures."

Outside of acting, she directed episodes of "Empty Nest," "Sister, Sister," and "Sabrina the Teenage Witch."

He wasn't very smart, and said that every teacher "flunked me at least once."

He guest-starred on series like "Diff'rent Strokes," "Cagney & Lacey," and "MacGyver." The actor portrayed Gerald Golden on the Emmy-nominated series "The Paper Chase," too.

Tucci also had a minor role in the 2013 comedy "The Heat," which starred Melissa McCarthy and Sandra Bullock.
