From Comic Con, why Matt would like to see the Doctor's dark side grow:
On his future hopes:
Matt, fezzes aren't stupid...
"There's a lot of blood on the Doctor's hands, and I think that's why
he's always so bubbly -- because he has to keep going,"
"Rule No. 1: The Doctor lies -- that's gonna be explored,"
On THE FEZ!!!:
"That was me bleating on to (executive producer/head writer Steven Moffat) that I wanted to wear a hat, so he gave me the most stupid hat possible,"
"Everyone has their Doctor. Hopefully in 20 years there'd be a Doctor Who panel with the panelists saying 'Matt Smith is my Doctor'"
Matt, you're my Doctor already...!
