In this video, we explore the story of Susan Ross, George Costanza’s unlucky fiancée, played by actress Heidi Swedberg. Introduced as an NBC executive, Susan quickly became entangled in George’s disastrous life, suffering indignities at every turn before returning in Season 7 as his bride-to-be. What should have been a hilarious long-term arc turned into a behind-the-scenes headache for Jason Alexander, who admitted he found it nearly impossible to find comedic rhythm with Swedberg. His frustrations grew as the season wore on, and soon Jerry Seinfeld and Julia Louis-Dreyfus found themselves echoing the same complaint.
Larry David, ever willing to lean into the show’s darkest instincts, seized on an offhand joke from Louis-Dreyfus about “killing” Susan and made it a reality. The result was the infamous Season 7 finale, “The Invitations,” where Susan died from licking toxic wedding invitations. To viewers, the scene was shocking, awkward, and oddly hilarious—perfect Seinfeld comedy. But behind the laughter was the reality of a cast who simply could not adjust to their co-star’s style.
Jason Alexander later expressed regret about how his comments were interpreted, emphasizing that Swedberg was a kind and generous colleague whose acting approach simply clashed with the ensemble. Still, Susan’s fate remains one of Seinfeld’s most memorable moments, forever tied to the story of the one co-star that everyone hated working with.
