"There can be only one!" Sorry, wrong Christopher Lambert movie...
Considered by most historians to be the best pre-2000 video game movie, Mortal Kombat (1995) proved you really could make a not-bad live action movie based off a game.
As Gene Siskel said: "You had a better time, admit it, than you thought you were going to have at this picture."
Roger Ebert responded: "Well, since I thought I was gonna have a very BAD time, that would be true almost no matter what I thought!"
While we are no Siskel and Ebert, get over here as we engage with Mortal Kombat!
