Watch: 'Doctor Who' star Matt Smith at Comic-Con
As with Karen Gillan, this is the second one of these I've done with Smith in the last few months. The one in the spring was considerably longer (so much that we wound up splitting it into two different parts, here and here), but there were certain topics we couldn't discuss at that time, either to avoid spoiling people (what the Impossible Astronaut does to the Doctor by the lake in Utah) or because I didn't know then what I know now (River Song's true identity).
Smith was, as always, very enthusiastic and thoughtful about discussing the role of a lifetime. Hope you enjoy.
