What has Lee Byung Hun been up to?  Growing some swell facial hair and filming for 'The Magnificent Seven' with Chris Pratt!

The Hollywood star posted a picture of the two together, complimenting Lee Byung Hun with, "Chilling on set with Korean superstar and all around great guy Lee Byung Hun aka Billy Rocks of the Magnificent Seven. 800 horse falls!!! That's a new movie record!!!A horse fall is a stunt. When a stuntman falls off a horse. We've done over 800 on this movie!! So far so good. No injuries. Man or horse. This movie is going to be incredible. More to come!"
