That's what a substantial portion of the threads are in the Power Chamber though. It's Haitien and Immortal of Justice and a couple of others constantly copying and pasting random movie and television "news" from blogs and websites and posting it in the form of new threads. At it's worst, it was Haitien cut and pasting excerpts from Neil Gaiman's blog for no real reason. It ends up being nothing but clutter and often bumps threads with actual discussion off the front page.
I don't know if a whole subforum is necessary, but a stickied thread would be nice. I don't think having a general "Movie News/Trailers" thread would hurt.
And to be clear, I'm not talking about talk-back threads where people discuss a movie when it's come out. Those are fine by me. What I'm referring to are all of the "So and so says they want to be (character)" and "New Trailer for (some movie)" threads that seem to pop up on an almost daily basis. There's no reason to have a new thread for each Watchmen trailer.
