Saved by the Bell's Tiffani Thiessen Almost Played Rachel on Friends

​With many of our favorite TV shows, we can't imagine the main characters being played by anyone else but the beloved actors who brought the roles to life. For instance, Jennifer Lawrence ​almost playing Serena van der Woodsen on Gossip Girl? Can't imagine it. And for an even more classic show like Friends, it's hard to imagine Rachel Green being played by anyone other than Jennifer Aniston.

While on Nikki Glaser's SiriusXM show, Tiffani Thiessen ​revealed she almost landed the role of Rachel Green. Yep, that's right, the same Tiffani Thiessen who played another iconic character: Kelly Kapowski on Saved by the Bell.

"Did you know I tested for Friends, for Jennifer Aniston?" Thiessen said on the show. "I was just a little too young. I was a little too young to the pairing of the rest of them."

Thiessen did recognize Aniston's great job in the role, calling her "very, very funny."

Many other famous stars auditioned for some of the main roles in Friends. Eric McCormack tried out for Ross Geller before he landed the title role in Will & Grace; Jane Krakowski, of 30 Rock and Unbreakable Kimmy Schmidt, also auditioned for Rachel; Vince Vaughn wanted to be Joey Tribbiani; and Leah Remini almost scored the role of Monica Geller.

While there are countless talented actors out there, we don't think anyone would've done the job better than the six stars of Friends. The sitcom is still a major staple today, even nearly 15 years after it ended. The cast might have something to do with that.
