5. Terminator 2: Judgement Day
The Terminator series has a number of excellent chase sequences, but the best unquestionably comes near the beginning of Terminator 2, when the T-1000 outs himself as a killing machine to John Connor, at which point he is forced to flee on his piddly little dirt-bike. The chase begins with the T-1000 keeping pace on foot, before commandeering a lorry and pursuing Connor through the streets, while the T-800 (yes, that's Arnie), on his awesome Harley, attempts to catch up. Arguably the best moment comes when Connor rides his bike into the Los Angeles viaducts, assuming that he has evaded his pursuer, only for the lorry to come careening over a bridge and continue the chase. Just as it appears that John is about to be squished by the lorry, the T-800 shows up and saves John, placing him on the back of his bike and unloading enough shotgun shells into the lorry that the T-1000 loses control, and the vehicle promptly explodes. It's a stunningly-rendered scene that's insanely chaotic and inherently dangerous; we're scared for John, and we're thrilled when the T-800 shows up, shotgun twirling and all, to save the day.
