Curry?s Pennywise has become Internet shorthand for the very concept of a scary clown, and it?s arguably his most iconic role of all-time, depending on one?s opinion of Curry?s work in The Rocky Horror Picture Show. Oddly enough though, Curry has never really publicly discussed what it was like to play Pennywise, or his experience making IT as a whole. Thankfully, that?s all about to change, as Bloody Disgusting reports that Curry is set to participate in Pennywise: The Story of IT, an upcoming feature-length documentary looking at the creation of the miniseries.
