(Make sure to watch all the way to the end for a special little treat.)

In the Fall of 1990, 27 years(!) before his arrival on the big screen, Pennywise was unleashed on television audiences with a mini-series adaptation of Stephen King’s IT, and the upcoming documentary Pennywise: The Story of IT will be diving deep into the sewers of Derry to tell the true stories behind the clown that terrified a generation.

The filmmakers updated today, “Over the last year we’ve been building the script for the main documentary plus a variety of bonus feature material. Currently we’re working on the full rough cut of the documentary and are on track with our original post-production schedule. With hours and hours of interview and set footage + hundreds of behind-the-scenes photos, this documentary has been an enormous lift for our entire team. But, ultimately, we know the wait will be worth it and we’re so grateful for everyone’s continued support.”

The doc, they note, is “Coming later this year!“

Check out the brand new extended trailer below.

With over 50 interviews with cast & crew and over 700 never-before-seen photos from the production, the fan funded documentary from director Chris Griffiths aims to “tell a story heard by few and showcase a wealth of behind-the-scenes footage and photos seen by even fewer.”

From exploring the historical and cultural phenomenon of coulrophobia (the fear of clowns) to Tim Curry’s magical portrayal of Pennywise the Clown to the impact Vancouver (aka “Hollywood North”) had on the 1990 made-for-TV miniseries, The Story of IT will dig deeper into the Pennywise phenomenon than anything ever has before.

Pennywise: The Story of IT was written & produced by John Campopiano and Gary Smart.
