The idea of casting Steve Buscemi in the lead role came about when Scorsese mentioned wanting to work with the actor, whom Winter knew well having worked with him on The Sopranos . Winter sent the script out to Buscemi, who responded very enthusiastically . "I just thought,' Wow . I'm almost sorry I've read this, because if I don't get it, I'm going to be so sad .' My response was' Terry, I know you're looking at other actors'...and he said,' No, no, Steve, I said we want you ."' Explained Scorsese, "I love the range he has, his dramatic sense, but also his sense of humor ." </P> <P> Buscemi has won and been nominated for several awards for his portrayal of Nucky Thompson .
