If you want to see a martial arts film, this is a pretty good bet. The star is trained in Muay Thai instead of kung fu or any of the usual martial arts, so there's plenty of flying elbows and knees.

Don't be expecting any revelations from the script or story, but if you've ever wanted to see someone with his legs on fire flying kick someone in the head, this is the film for you.

Also has the wonderful line: "Don't have a wank. I don't want you to slip and die."

Ah, now there's a quotable line if ever I heard one

Aren't the Asgard supposedly technologically superior?

Imagine that coroner's report.

Cause of death: Slipped on own ejaculate.

I guess it's better than slipping on someone elses.

Trust me, I'm a doctor.
