The beloved sitcom Friends was known for its iconic cast, but the show also featured memorable guest stars who often stole the spotlight. These A-list actors brought excitement and new storylines to the show, making their appearances stand out even years after the series ended. One of the funniest guest stars on Friends was Jon Favreau, who played Pete Becker in season 3. Pete, a tech millionaire, briefly dates Monica and brings a wild energy to the show with his over-the-top personality. Another standout guest star was Winona Ryder, who played Melissa Warburton, Rachel's former sorority sister. Ryder's performance as the obnoxious Melissa, who pretends to have no memory of Rachel and her drunken kiss, is memorable and hilarious. Brad Pitt also made a memorable appearance on Friends as Will Colbert, a high school classmate of Ross, Monica, and Rachel who passionately hates Rachel.
The humor of Pitt's cameo was heightened by his real-life marriage to Jennifer Aniston at the time, making the scenes all the more hilarious. Another notable guest star was Bruce Willis, who played Paul Stevens, the father of Ross's girlfriend Elizabeth. Willis's tough action hero persona added a dynamic to the show and made his scenes with Ross particularly entertaining. Lisa Kudrow, who played Phoebe, also had a standout guest appearance on Friends as Ursula Buffay, Phoebe's twin sister. Kudrow's ability to play both characters and showcase the confrontations between them added an extra layer of comedy to the show. Gunther, played by James Michael Taylor, was a recurring character throughout the series who often stole scenes with his deadpan humor and obliviousness to everyone but Rachel. Other notable guest stars include Isabella Rossellini, Julia Roberts, and Elliot Gould. Each brought their own unique comedic talents to the show and left a lasting impression on viewers.
Alec Baldwin also made a hilarious appearance as Parker, Phoebe's overly positive date to the Gellers' anniversary party. Towards the end of the series, Danny DeVito made a memorable cameo as Roy, a stripper hired for Phoebe's bachelorette party. His performance as a past-his-prime stripper added a comedic twist to the storyline. One of the most unexpected and memorable guest appearances on Friends was by Billy Crystal and Robin Williams. The two comedic legends improvised their scene, creating a bizarre and dramatic conversation that momentarily steals the attention away from the main story. Lastly, no list of guest stars on Friends is complete without mentioning Maggie Wheeler, who played Janice. Janice's recognizable voice and her catchphrase "Oh. My. God!" always brought laughs and put the friends on edge whenever she appeared. Overall, Friends had a talented lineup of guest stars who added humor and excitement to the show. Their performances continue to stand out even years after the series ended. Friends is currently streaming on Max.
