Grumpy old comedians! 

Ben Stiller and Kristen Wiig were drastically aged for their new film, The Secret Life of Walter Mitty -- and they don't look too happy about it.

The stars were almost unrecognizable on Thursday dressed in major old age makeup to film scenes on a snowy set in NYC. The director of the film, Stiller, 46, was covered in wrinkles, had a grey comb over and wore tiny round glasses. To complete the look, Stiller styled a tiny red bowtie and scarf.

But Wiig didn't get a much younger look. The 38-year-old actress, who announced her departure from Saturday Night live in May, had a full head of curly brown hair, but a very wrinkly face (made worse when she scowled for the camera.)

The Secret Life of Walter Mitty is a remake of the 1947 movie starring Danny Kaye. The film is about a shy magazine photo manager, who fantasizes about a heroic life in daydreams, but is sent on a real-life adventure when a negative goes missing.
