It's in Korean, but if you don't understand Korean I think it's not that hard to sort of guess what they are saying. Plus there are weird audience background noises, so you can sort of tell when it's a funny moment or a sad moment... I think this was probably shown live in a studio or something.
There's an English subbed version, but only the first half has been subbed.
The movie is starring Park Yoochun of the Korean boyband Dong Bang Shin Gi.

It takes a while to load, especially during peak hours, so be patient! It's worth the wait!
I just wish someone would tell me what song DBSG is singing in the opening of the movie...
