If you've seen any action movies in the last five years or so, chances are you've seen parkour, whether you knew it or not. It typically shows up when someone is being chased or trying to get somewhere quickly.

"I was in the military overseas when I stumbled across it on YouTube, and some movies," said Devin Gregoire, who is teaching a parkour class through Las Vegas Movie Mastars Action & Entertainment Nexus, 2700 E. Patrick Lane, No. 16. "I saw it in 'District B-13' and a few foreign movies."
