Emma Stone, Edward Norton, and Zach Galifianakis star in the much buzzed about dark comedy Birdman, which also marks the restore of its star Michael Keaton to the big screen. While the film deals with an aging star’s struggle with his career, ego, and personal life as he tries to mount a Broadway show, one of the most memorable scenes in the movie has Keaton running around Times Square with only his tighty whities to support him.

In honor of this cinematic spectacle, we challenged the cast (which also includes Naomi Watts, rising star Andrea Riseborough, and The Office’s Amy Ryan) to identify other actors who dared to bare their briefs on screen, including Tom Cruise, Jason Segel, Rhys Ifans, and Birdman’s own Zach Galifianakis, who believes he’s very skilled at ID-ing his own body.
