Danny DeVito Almost Played George on Seinfeld

Long before Frank Reynolds became a staple on "It's Always Sunny in Philadelphia," Danny DeVito was considered for a prominent role on another iconic sitcom: "Seinfeld." The role in question was that of George Costanza, a character now indelibly linked to Jason Alexander. This casting possibility was revealed by Alexander himself during an interview. He stated that DeVito was a serious candidate for the part, alongside other actors like Chris Rock. Alexander suggested that DeVito likely declined the role because it was perceived as a 'sidekick' position, which might not have aligned with his career aspirations at the time. The decision not to cast DeVito meant Alexander would go on to define the character of George Costanza.
