Rich Walton witnessed the Lucha Libre explosion while making a documentary about the sport, "Life Behind the Mask." He recently invited all his masked friends to a red carpet premier in Long Beach.

Lucha libre has remained popular since the 1800s due to its array of colors, pageantry, and of course, the vibrant and creative lucha mask.

But for many fans of lucha libre, the importance of the mask was established by the man most consider to be the biggest wrestling star Mexico has ever seen; El Santo. Even if you have no knowledge ...

He’s lucha libre royalty, a Los Angeles-based luchador whose father was an acclaimed wrestler in Mexico known as El Chivo. Kayam, 63, was getting ready to put up his mask.

According to Magno, a mask-vs-mask match in lucha libre means whoever wins will catapult into the top ranks of the sport while the loser may never be heard from again.
