The new Doctor Who is embarking on a special tour of the UK, to meet his fans and show off screenings of the first episode.
Matt Smith and his on-screen helper Karen Gillan will be travelling the length and breadth of the UK on a Tardis-themed bus.
Some fans will be able to meet the 11th Doctor and see a premiere of the first episode he stars in.
The three-day voyage begins on 29 March 2010 and the first stop is Belfast.
Sadly you can't apply for tickets. But lucky school kids will be chosen by the BBC, according to where they live.
