I attended an advanced screening of the Doctor Who Christmas Special, “The Snowmen,” along with Matt Smith (who is surprisingly thin), Jenna-Louise Coleman (who was surprisingly my height—or lack thereof), producers Stephen Moffat and Caroline Skinner (who were unsurprisingly British), as well as Neil Gaiman (whose attendance was a surprise), and John Hodgman (whose attendance should have been a surprise, but actually it makes perfect sense).
