The impetus for telling this story was that Howard said, 'Julia Louis Dreyfuss told me you all wanted to kill her' So I told the story to try and clarify that no one wanted to kill Heidi." Swedberg played Susan Ross, George's fiancee, who eventually dies by poisoning after licking all the envelopes on their wedding invitations. I just felt I was on uncertain ground in how to play off that character and I was always concerned that it wasn't working. He also clarified that when comments were made about killing off Susan, they were directed strictly toward the character and not toward Swedberg herself, who Alexander writes, "was generous and gracious and I am so mad at myself for retelling this story in any way that would diminish her." He closed by personally apologizing to the actress and writing, "You are a sweetheart. I actually launched into this on Stern to defend you. But this is why I'm not a lawyer." When Stern steered the topic toward rumors that Alexander couldn't stand actress Heidi Swedberg, the actor was quick to clarify: "She's a terrific girl...I couldn't figure out how to play off of her." And I went, ‘Oh, great. Following filming, Alexander said, the core cast would go to dinner, and Alexander complained about his lack of chemistry with his on-screen fiancee. It wasn't until Jerry Seinfeld and Julia Louis-Dreyfus performed extensive material with Swedberg in Season 7 that they took Alexander's concerns seriously. "Julia actually said, 'I know, don't you want to just kill her?,'" Alexander said, which he says gave show runner Larry David the perfect plot line for his then-undecided season finale.
– In Seinfeld's seventh season, George Costanza's fiancee, Susan, was killed by toxic glue on their wedding invitations—and the man who played Costanza has now revealed that the cast had plotted to have her killed. Jason Alexander told the Howard Stern Show yesterday that while Heidi Swedberg, who played Susan, is a "terrific girl," there was a serious lack of chemistry between her and other cast members, Mashable reports. "I couldn't figure out how to play off of her," Alexander explained. "Her instincts for doing a scene, where the comedy was, and mine were always misfiring." Alexander says he complained about Swedberg and discussed her character's fate at dinners with show co-creator Larry David and other cast members who were finding Susan scenes difficult, ABC reports. Julia Louis-Dreyfus said, "I know, don't you want to just kill her?' And Larry went, 'Kebang,'" Alexander recalled. "Every time I tell this story, I cringe. Heidi is the sweetest." After her character's cruel death, Swedberg had roles in shows like Bones and is now a ukulele teacher, reports ABC. In the same interview, Alexander said other actors up for the Costanza role included Chris Rock, Paul Shaffer, Steve Buscemi, and Danny DeVito, who was offered it but turned it down, reports Entertainment Weekly.
