Is there anything more iconic than binging all ten seasons of Friends? If you're like us at Fun Cases, you probably know every episode by heart and can't get enough of the Central Perk gang. But let's be honest, sometimes it's the guest stars who truly steal the show! From Tom Selleck's unforgettable role as Dr. Richard Burke to Brad Pitt’s hilarious guest appearance, these guest stars have left their mark on one of the greatest TV shows ever. So, let's dive into a list of some of the best guest stars on Friends. And don’t forget to check out our awesome Friends merchandise to keep the fandom going strong.

1. Tom Selleck as Dr. Richard Burke

Tom Selleck’s smouldering Dr. Richard Burke made quite the impression. With his fabulous moustache and undeniable charisma, Dr. Burke was a heartthrob not just for Monica, but for fans everywhere. His on-again, off-again relationship with Monica added a mix of drama and depth to the series. Don’t get me wrong, Chandler and Monica are #RelationshipGoals, but Dr. Burke? He was something special.

2. Aisha Tyler as Charlie Wheeler

Entering as a palaeontology genius who dated both Joey and Ross, Aisha Tyler brought brains and beauty to the Friends universe. Her character was a breath of fresh air, and her interactions with the gang were both intelligent and humorous. Plus, how many people can say they dated two of the six Friends? Total legend!

3. Brad Pitt as Will Colbert

Brad Pitt’s cameo as Will Colbert was nothing short of epic. Playing a former high school classmate who, along with Ross, co-founded the “I Hate Rachel Green Club”, his Thanksgiving episode had us in stitches. How ironic is it that he was married to Jennifer Aniston in real life at the time? Talk about awkward!

4. Reese Witherspoon as Jill Green

Reese Witherspoon dazzled as Rachel’s spoiled younger sister, Jill. Her character added an extra layer of humour and sibling rivalry. Reese’s portrayal of Jill was both hilarious and captivating, providing some unforgettable scenes with the Friends crew. After all, who could forget the famous “That’s not how it works!” line?

5. Paul Rudd as Mike Hannigan

Paul Rudd’s Mike Hannigan was the perfect match for Phoebe. His kind eyes and quirky personality made him a fan favourite. That piano-playing, comic-reading, genuinely nice guy stole our hearts and gave Phoebe the happily-ever-after she deserved. Team Mike all the way!

6. Christina Applegate as Amy Green

If you thought Reese Witherspoon was amazing, then Christina Applegate’s turn as Rachel’s other sister, Amy, was just as memorable. Playing the self-involved and tactless Amy, Christina delivered some of the show’s funniest lines. Her character’s cluelessness about life and relationships made every scene she was in pure comedy gold.

These guest stars truly added some sparkle to an already shining show. Whether it's Tom Selleck bringing the heat or Paul Rudd’s heart-melting charm, they each left an indelible mark on Friends.
