Far too late for this movie. I'm also not seeing why a script couldn't have been knocked out ages ago. It's only sword and sorcery fantasy. Get each basic class as a main character looking for some magical artifact to destroy evil guy of the day. Throw in a few distinctive areas from the game, a dumb love interest sideplot and a minor charcter to take a few pratfalls. Blow some things up and you're done.
It's Hollywood, they are going to ruin it with a formulaic plot and wooden characters, the least they could do is make it quickly.
