Jason Alexander Confesses The One 'Seinfeld' Castmate Who Was 'Impossible' To Work With

Seinfeld was the sitcom of the ’90s, with a cast of characters each more ridiculous than the next. But while the actors who starred in the iconic show may have stolen our hearts, things behind the scenes weren’t always as affectionate. In fact, Jason Alexander, who played George Costanza, has revealed that one Seinfeld actor was an absolute nightmare to work with. The funnyman did not  go easy in his comments—and fans are now looking at the show completely differently.

A ravenous fan base keeps searching for new tidbits of information about their favorite show, and the stars aren't afraid to deliver.

Jason Alexander has been one of the most vocal members of the Seinfeld cast. Maybe it's because no one else embodies the show quite like George. And even 20 years on from the end of the sitcom, Alexander deals with regular questions about his days on set. Ones about how he got on with his castmates, for example...

After nine years, when the show ended, we kind of went, ‘Oh, bye, see ya!’" And compared to some other interviews he'd given, this answer was pretty tame!
