Tom Cruise braved freezing London weather on Thursday with his own portable heater for the premiere of "Oblivion."<br/> <br />The film follows the last two remaining humans on Earth trying to maintain the defence of water supplies from a mysterious alien species. They both can't remember their past, but when a space craft crashes, the sole survivor triggers memories and feelings within them.<br/> <br />Cruise is looking on top form in the movie - some say as good as he looked in Top Gun.<br/> <br />SOUNDBITE (English) Tom Cruise:<br/> <br />"Thank you very much, thank you. You know, working... I just work and I'm an actor so I've got to train and I'm an athlete and the kind of characters and films and... just making a movie you've got to be fit and I've just trained my whole life. It's nothing special. I don't know how. I don't sleep much either, but thank you for saying that, thank you."<br/> <br />"Oblivion" may see Tom flying around in a space craft, but how out of this world is he in reality?<br/> <br />SOUN
