Source Code is the second film from Duncan Jones, who previously brought us Moon and who was brought to us in part by David Bowie, him being his dad and all [/obligatory Bowie mention]. Firstly, I enjoyed this much more than Moon , but then I took the slightly heretical position of not enjoying that movie all that much. In fact, the same applies to pretty much all of the bona fide, classic dialogue-based sci-fi movies that I've seen - 2001, Solaris, Silent Running ... I've clearly been raised on an unhealthy diet of space opera, action and blockbuster FX, for which I can only apologise. Anyway, Source Code on the surface is a big leap into the mainstream by Jones - big budget, A-list star, plenty of explosions (well, technically the same explosion but it does happen LOADS of times). But even from the opening titles, sweeping aerial cityscapes accompanied by pleasingly old-school bombastic music, you get the feeling that this is a filmmaker who cares. Jake Gyllenhaal helps...
