I guess it's possible that Men In Black 3 could make money at the box office. I have a bad feeling about it, though. The threequel that nobody wanted has not been an easy production; a scheduled gap in filming (for tax purposes. Seriously) reportedly led to big script changes and, depending on who you believe, large segments of the movie were reshot. The aliens that Rick Baker created are almost certainly being replaced with CGI. Will Smith had a set torn down and rebuilt to fit in with an improv he did. The budget is well over 200 million dollars, and I guarantee that's a low, low estimate (although those aforementioned tax breaks will help).
To prime the pump Sony has released these teaser posters for the movie, which are sort of similar to the posters for Tinker, Tailor, Soldier, Spy and Mission: Impossible: Ghost Protocol in that they have character faces staring straight at the camera but the faces are made up of text. Numbers in the case of the first two, and the movie title in this case.
Does this work for you? Are you getting psyched for MIB3? I'll admit that the idea of Josh Brolin as a young Tommy Lee Jones (there's a time travel element in this one) is interesting, but otherwise... I could wait for cable.
