Tron: Legacy (2010)
Apart from The Dude, a badass Daft Punk soundtrack and flying discs of doom, the best thing about Tron: Legacy has to be the Lightcycle bikes. These light-lined beasts produce a destructive field making their gaming arena lethally entertaining. The real-world version might not be so dangerous but its looks are still killer. To get an idea of the effort that went into creating spectacular CGI sequences like the lightcycle battle: this film was shot in 64 days, the special effects took 68 weeks.
