Well, Fat Harry
over at AICN makes a point which is really rather obvious but he does it so succinctly in his Fat Harry style that it bears quoting:
All the doubting thomases should pay attention to one thing! Paramount is having HIGH PROFILE screenings beginning on April 6th in Austin and April 7th in Australia... and for the next 30 days leading up to release - they'll be screening this movie around the world. Here in the U.S. and throughout Asia and Europe - and even to US Troops in the Gulf.
This is only something a studio does when they know they have A BIG DICK! They whip it out and show it a bunch, because THIS DICK DOES NOT COME UP SHORT!
