I'm with you Shuey, kind of. Part of me wants to know more about the Universe, so wouldn't mind a movie, but I expect they'll go with Shepard being the star and that is something I don't want to see because so much of Shepard is up to the person playing.
they've already stated that they aren't looking to make a movie about shepard as they want to keep (key word is want) that as YOUR story that you shaped. the most likely canadates for plot of the film would be the books, or humanities rise to spaceflight
and use of the relays (basicly recent history) or, the hardest thing to do, something that goes on after the trilogy.
also they aren't showing any trailers as I understand it just discussing probably plots and settings etc. as I believe that article (if its the same one I read) mentions it will be Casey Hudson with the films writer(s) there to do a pannel on the movie.
Mass Effect is going to be ruined. They will use this an an excuse to have a *** scene between a human and an alien. It will be stupid, ridiculous...they wil try to make it as 'cool' as they posibly can, and it will be ruined.
