As I played through Brink, I felt that it could definitely be turned into a film. The story is compelling, in my opinion, and with some real character development, I think it could make a good action flick. It would have excitement and great action sequences, especially mixing parkour and gunplay (Casino Royale showed a glimpse of that). Plenty of drama could be presented through the characters and their struggles within their own factions and then between the Security and Resistance. Don't forget throwing some female fighters in as well, appeasing the women crowd, possibly developing a romance, if the need arose.
I'm aware that the chances of this happening are slim to none, and video game to movie adaptions svck generally, but if it was done right.....
Does the community here think this has legs? It's a good, solid story, with two sides that can be presented equally, leaving the audience to side with who they want.
