I think everyone should see their favorite movie on a cinema screen at least once in their lives.
Our local Cineworld did a one-off showing of 'The Thing' a couple of years back. There's not one single frame of that movie I'd change — it's fantastic, and even better on a big screen.
Slightly off topic (but I'll come back to it in a mo'), I recently bought the box-set of both Thing films. Watching the original on my widescreen TV on the PS3...it appeared letter boxed. I don't mean in the desirable 'fill the screen' way but actually so you saw a smaller screen within your own TV screen with black all around. Black borders at top or bottom is understandable as I understand that with many films the aspect ratio doesn't quite match that of the widescreen TV and it doesn't particularly bother me, but all around indicates it should fit the width at least. Tweaking the display settings didn't help much. Any suggestions appreciated.
Back to topic, I confess I never made it all the way through either. I actually found some sequences in rather boring.) Sorry. I do remember being fascinated by that very odd bit at the end though (and I liked Hal stuff. It's mainly watching from the start which dragged.) I'd definitely coming consider giving it another chance from the beginning on the big screen.
