What movies got postponed because of 9/11?

I saw something on the news at a restaurant last night about movies whose release schedules have been pushed back because of the terrorist attack. (Or not; my hearing’s not so great.)

On the list, as far as I could tell, was the next Schwarznegger flick Collateral Damage (which, AFAICT, was going to, um, bomb anyway), Big Trouble (nuclear bomb being slipped onto a domestic flight, and some other movie that eludes me at the moment.

So what’s the deal with these movies? How far back were they pushed, and are there any others that might be?
