Here’s the first full trailer for Brick Mansions, one of the final films completed by Paul Walker before he was killed in a car crash in November. Walker stars in the American-ized remake of the Paris-set District 13 (Banlieue 13) as an undercover cop trying to take down a crime lord in a dystopian Detroit. The actor was in most of the scenes and had finished looping the pic only three days before his death. Camille Delamarre directs from a script by Luc Besson and Bibi Naceria. RZA and Robert Maillet also star. Relativity releases the pic on April 25.
