ANCHORAGE, ALASKA — Passengers on an Alaskan Airlines flight were more than a little shell shocked after a man started running through the plane in his birthday suit.

The Mercury News reports that Nick Steffl first noticed the dude while he was watching James Franco's The Disaster Artist while still fully clothed.

He said he suspects the movie might have played a role in the nudity that ensued, since one scene shows Franco in all his naked glory.

Retired Alaska senator Johnny Ellis was also on the flight. Both he and Steffl witnessed the man bolting to the cockpit whooping and hollering, before turning back toward the rear.

Steffl stood up to confront the man, asking him what he was doing and then slapping him across the face when he gave a wisecrack response.

Seconds later, a second passenger who might've been the fella's dad restrained and then took him to the crew area.

Despite being out of sight, the naked man shouted crazy things until the plane landed in Anchorage 45 minutes later.

Police waiting at the gate took him into custody and later brought him to a hospital.
