That could be cool. I never played Halo so this would be a good way for me to get the story. There shouldn't be any budget concerns, so if nothing else, we can at least expect good special effects and design.
Freaky...I watched The Beach right after I saw 28 Days Later...well not right after...saw Bad Boys 2 in between the movie marathon. Didn't realize was same screenwriter...whoa...blows my mind...damn all I ate that day was an apple I stole from my roommate...but it was Halloween so it was ok...that girl was so drunk...ah good times...anyway...
I seriously dislike video game movies (except for Mario which everyone else hated). I see this as being like Starship Troopers except the aliens are cute little buggers inside of cute giant insects.
And "The Station" accordingly is a big-ass hoe, whereas "The Cube" is a 24-pack of beer with two layers of 12 cans each. Put the three together and you got yourself one hell of an afternoon.
I think a good movie depends on who is directing, hopefully they can get a good director. For example I am a big Star Wars fan, but if someone else besides George Lucas was directing, the movies could be a lot better. My vote is for Steven Spielberg.
