I just took a look at the WIKI page for Extinction and it links to an IGN interview with Anderson. He's writing (but not directing) and the film will take place in both Alaska and Tokyo. It will continue to follow both Alice and Claire and its similar to RE2 and darker (I'm hoping that means its closer to the game RE2 and not Apocalypse).I thought about Wesker, and there really was no need to put him in the film at all. He does nothing except bitch and moan. He's wearing the shades... but why? He was wearing them throughout the series because he was masking his red eyes after injecting himself with one of the viruses. Here he is head of Umbrella... how? lol.
Wesker was supposed to be the main enemy in the 4th one set in Toyko so they introduced him in the 3rd movie. However I don't know about those plans anymore.
I thought I heard Mila wasnt going to be in anymore Resident Evil films. Glad that seems to not be true and she will hopefully be in any fourth film as I liked her performances.
I enjoyed all three movies. I found them entertaining and Alice a good character. What I didnt really like was the animated one, I didnt think either the animation or voice acting was particularly good.
