No problemo! It was a real treat to get a bit more of him, and he really sunk into the role right away. I realize that the actor can’t take credit for the lines themselves, but his delivery was phenomenal. Not too much like other actors, but enough in the same vein that it’s recognizable. Really well done given what he had to work with.
I hear that the audio dramas from Big Finish are uniformly excellent; I’ve really been meaning to check them out and have just gotten behind on so many things that I haven’t, which sucks.
Lego, I’d recommend popping into at least S7 to catch Episode 1 (“Asylum of the Daleks”), Xmas Special (“The Snowmen”), 6 (“The Bells of Saint John”), and 13 (“The Name of the Doctor”).
If you really want to, I’d also snag S6 E1/2 (“The Impossible Astronaut / Day of the Moon”), 5/6 (“The Rebel Flesh / The Almost People”)*, 7 (“A Good Man Goes to War”), 8 (“Let’s Kill Hitler”), and 13 (“The Wedding of River Song”) to pick up on some plot elements from that season that become relevant (some background characters, key lines of dialogue, etc.
Finally, if you enjoyed the Rory/Amy companions, you’ll want to snag S7 episodes 4 & 5 (“The Power of Three” and “The Angels Take Manhattan”) for closure, if said episodes can claim to provide that.
These are ordered in terms of descending importance to the Anniversary Special (in terms of plot-points we’re reasonably sure will be explored there; it’s likely that Moffat, the writer, will also draw in elements from elsewhere unexpectedly, perhaps going quite far back into even Russel T. Davies’ run or before), with the exception of the starred episodes (S06 E05&06), which are recommended mostly to ensure the following episode (07) makes the most sense possible.
