In 'Tinker Tailor Soldier Spy,' Gary Oldman plays a retired spy set on hunting down a mole inside British intelligence. Now, Moviefone is offering you the chance to do a little spying of your own -- at the official Los Angeles premiere of the film. Next week, we'll be giving away two pairs of 'Tinker Tailor' premiere tickets. To enter, simply head over to the Moviefone Facebook page and tell us -- in 100 words or less -- who your favorite on-screen spy is, and why.
