(Newser) – 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.
