9. Portal
To a certain extent, this is actually an opportunity for two good roles for women thanks to lab rat protagonist Chell and creepy female-voiced artificial intelligence GLaDOS being the only real characters. Hollywood continues to churn out movie versions of video games, despite a near total lack of quality end product, so they're always on the look out for viable new options. Portal, a teleportation based puzzle game spun-off from Valve Games' Half-Life, wouldn't seem like an obvious choice for a narrative film, but it's popular acclaim, tone and sense of dark humour have already resulted in some well-regarded
fan shorts.
How likely is it? Earlier this year Star Trek/Wars director J.J. Abrams and Valve founder Gabe Newell announced that they were talking about possible future collaborations on big screen versions of both Half-Life and Portal. Abrams' attention is understandably pretty focused on a galaxy far, far away right now, but he has always been happiest juggling multiple projects as a producer and overseer, so expect him to play that role on any Portal film rather than directing himself. To be honest, a Half-Life movie would seem an easier sell in terms of a more obvious narrative structure, so we'll probably see that made long before a feature length Portal.
Who should star? Chell is a voiceless first person protagonist, so barely actually appears visually or vocally in the game. This means that casting directors actually have a pretty free reign when it comes to picking an actress to play her. Looking for someone with a pedigree as a tough, resourceful action girl, they could do worse than Michelle Rodriguez. With experience exploring sinister science facilities in game adaptations thanks to Resident Evil (dreadful movies, but one of the very few ongoing successful franchises with a female lead), Rodriguez showed great range and quality as an actor in Girlfight.. and let's not forget that she was the sole human female in the biggest movie of all time, Avatar.
