Steven Seagal -- star of action movies like Under Siege and Exit Wounds -- is apparently such a tough guy, he doesn't even have to try to stop the bad guys. That's the premise of the latest commercial for Mountain Dew from BBDO/New York. Directed by Traktor via production company Partizan, the spot shows Seagal walking in on a robbery-in-progress at a convenience store. Oblivious, he picks up a Mountain Dew and ends up inadvertently foiling the criminals with his every move. The clerk is grateful, of course, but not exactly starstruck.
