At 26 years old, Matt Smith becomes the youngest actor ever to take control of the TARDIS.

He's the first "Generation Y" doctor.
After the Gen-Xers Christopher Eccleston and David Tennant, we're now set to see the adventures of a 80s child with more money than sense, a lack of appreciation for the hard times, and a beyond-sensible interest in iPhones, Robot Chicken and hair pomades.
