Central Cinema here in Seattle shows this [your favorite description of a trainwreck] monthly. Central even held a screening of Dude Bro Massacre Party III with Greg Sestero in attendance doing a stage read from an original copy of the script for “The Room” (which if you can believe was even more incomprehensible than the film).
I would also highly recommend reading Greg’s book The Disaster Artist: My Life Inside The Room, the Greatest Bad Movie Ever Made which had me continually laughing as I tried to comprehend how this could ever have happened.
Disclaimer: I am an avid attendee of Central Cinema but do not receive any compensation from them for praising their glory. Also, I do not personally know Greg Sestero, I just really liked his book.
