Daleks, Tardis, and Weeping Angels. Okay, have we netted all the Doctor Who fans with that geek bait? Good! Because tomorrow we’ll be interviewing Matt Smith, the man who plays the new and eleventh Doctor (his practice begins on BBC America this Saturday night at 9 p.m.), and we want to ask him your questions. So put them in the comments below and we’ll fire them at him; his answers will appear this Friday on Vulture. The nerdier the better: When you sign on for a job like playing Doctor Who, you’d better be prepared to come with some deep knowledge.
