Don't believe any rumors about Ridley Scott’s Alien prequel being pushed back a year. Our sources tell us Fox is definitely making it and that production starts in March. Last Thursday, an online report stated — incorrectly, it turns out — that the releases of Scott's back-to-back prequels were being moved to 2013 and 2014. Not so. Here’s what’s really going on: Insiders familiar with the situation tell us that this is merely the echo of a failed effort to cast the movie with Leonardo DiCaprio. Initially, there was some talk at Scott Free of pushing back production to accommodate DiCaprio's schedule, so that he could shoot Clint Eastwood’s J. Edgar Hoover biopic back-to-back with Scott’s two-part Alien prequel. That, apparently, will not be happening — there will be no "push" to next year.
