Kristen Wiig is a Dream at the New York Premiere of ‘The Secret Life of Walter Mitty’

Kristen Wiig got all dolled up last night for the premiere of The Secret Life of Walter Mitty in New York City.

Wiig, who stepped out in a gorgeous champagne frock with metallic detailing, was joined by her co-stars Ben StillerAdam Scott and Sean Penn for the red carpet affair during the 51st New York Film Festival.

The fantasy comedy-drama is based on James Thurber’s 1939 short story of the same name. The Secret Life of Walter Mitty was first adapted into a film in 1947, with actor-singer Danny Kaye in the title role.

The Secret Life of Walter Mitty, starring Kristen Wiig and Ben Stiller, opens stateside on Christmas Day.
