The film that looks like it could be the most fun this week is The Good, The Bad, The Weird, which looks kind of like a Korean take on Indiana Jones in full-tilt boogie mode. It will be in a limited number of theaters, but it will be available as part of the IFC On Demand service, available through a number of cable companies including Comcast.
If you don’t have access to that film, it looks like The Losers might make an acceptable substitute. It is not quite genre, but still looks like it could be fun.
