It’s hard to believe the remake of the 1947 comedy The Secret Life of Walter Mitty is finally in front of cameras. The film has been in the works for well over a decade and gone through a multitude of bankable lead actors including Jim Carrey, Mike Myers, Owen Wilson, Will Ferrell, and Sacha Baron Cohen, but Ben Stiller turned out to be the last man standing, and not only is he starring in the flick, but he’s also directing it. The plot centers on a LIFE Magazine proofreader (Stiller) who, incapable of standing up for himself in the real world, retreats to a fantasy where he becomes his poised, confident opposite. While we previously saw Stiller and co-star Adam Scott playing with a Stretch Armstrong doll, the latest photo is even stranger as it shows a nearly unrecognizable Stiller in old age makeup alongside Kristen Wiig. I’m not sure where this scene is in the movie (I haven’t seen the Danny Kaye original), but kudos to the makeup department.

Hit the jump to check out the set photos. The film also stars Shirley MacLaine, Patton Oswalt, Kathryn Hahn, and Sean Penn. The Secret Life of Walter Mitty is due out December 25, 2013. [Update: We’ve removed the unofficial images.]
