(Photo: Aby Baker/Getty Images)I bet you recognize Kristen Wiig (left) -- in spite of the aging makeup job she's donning to make her look like an elderly woman.
But who is that to her left? Believe it or not it's Ben Stiller. Wearing a mask of wrinkles and age spots, glasses, and silver hair with a receding hair line, Stiller is simply unrecognizable.

While also wrinkled, Wiig, 38, can still be deciphered as she wears an emerald over coat and matching hat.
Both comedic actors were spotted on the set of "The Secret Life of Walter Mitty" as they filmed in New York on Wednesday. Stiller, 46, is also directing the film, about a shy and imaginative photo editor who is forced out of his daydreams and into a real-life adventure when a negative winds up missing.

And from the look of the wardrobe style on set, the remake will also be set in the '40s. (The story originally spawned from a short story by James Thurber.)
The new "Secret Life" also stars Shirley MacLaine, Patton Oswalt, Adam Scott and Kathryn Hahn.
