'Seinfeld's' Cast Couldn't Stand Working With One Of The Show's Most Memorable Guest Stars!

Seinfeld, one of the most beloved sitcoms of all time, had some surprising casting struggles. Jason Alexander recently revealed that he found it hard to work with Heidi Swedberg, who played Susan Ross. He claimed their acting instincts were diametrically opposed, and Julia Louis-Dreyfus even suggested killing off her character so they wouldn't have to work with her. Susan was ultimately written out of the show by licking too many toxic envelopes. Although fans were shocked at her death, Heidi Swedberg took it in stride, and Alexander apologized for any offense caused.
