Almost two decades after the hit TV series, "Seinfield," celebrated its final episode, issues regarding the working relationship among the cast and crew are now surfacing. In a recent interview with Howard Stern, Jason Alexander revealed that some members of the cast decided to simply kill off the character of Heidi Swedberg because she did not mesh well with the rest of them, according to The Hollywood Reporter.

In the series, Alexander's character, George Costanza, and Swedberg's Susan Ross were engaged to be married following three episodes since the latter was introduced in the show. In an unexpected turn of events, however, Susan was killed off the series. By way of explaining her departure from the show, the writers decided to let the supposedly future Mrs. Costanza die due to the poison she licked from one of the envelopes used to send their wedding invitations.

While the plot twist was created in a satisfying manner, Alexander now reveals that it was not part of the original plan. According to him, the decision to kill off Swedberg's character came after the rest of the members of the cast eventually agreed with him that it was difficult to work with the actress.

Alexander told Stern that he "couldn't figure out how to play off of her. Her instincts for doing a scene, where the comedy was, and mine were always misfiring. And she would do something, and I would go, 'OK, I see what she's going to do - I'm going to adjust to her.' And I'd adjust, and then it would change," according to Time. He also said that working with Swedberg was "impossible." Hence, when "Seinfield" star Julia Louis-Dreyfus jokingly suggested to just kill off Swedberg's character in the series, the show's creator along with Alexander himself immediately agreed.
