Some images from the set of a couple of upcoming films have surfaced online.  First up, though we just saw the first trailer for the film last week, Brad Pitt is back on set doing reshoots for director Marc Forster’s zombie apocalypse pic World War Z.  We know that the third act was reworked by Damon Lindelof and Drew Goddard, so presumably these images are from the film’s finale – which explains why Pitt is so bloody.  World War Z opens on June 21, 2013.Additionally, following a five-year break from acting Jared Leto is back in a big way on the set of the AIDS drama The Dallas Buyers Club.  Based on a true story, Matthew McConaughey plays a Texas electrician who, after being diagnosed with AIDS in 1986, began to smuggle alternative and illegal treatments into the US and into the hands of other patients.  We previously heard that Leto would be playing a flamboyant cross-dresser with HIV who helps McConaughey’s character, and these set photos prove that the actor isn't doing this thing half-heartedly.  Hit the jump for the images from both films. [Update: We've removed the unofficial images.]Fun fact: producer Cassian Elwes revealed on Twitter that McConaughey is now down to 141 pounds.removed image
