Lockout really does sound like Escape From LA in space. Can't say many of them catch my interest, I think i'll be buying more older movies again this year. Prometheus might be good, Total Recall looks good visually so let's hope it lives up to it. Ironsky and Cosmonaut might be good since they're not backed by meddling big studios.
The problem with The Cosmonaut is that it's influenced by Solaria. Solaria at 90 minutes to me is a snorefest, and is as action packed as The Matrix compared to the original 3 1/2 hour Russian version, which takes them 2 hours just to get into space.
