Who is Marcus Wilson, and what was his role? I meant in the show, btw, not in the behind the scenes love triangles (or should that be love pentagons?!).
One of the ever lengthening line of (ex)Producers. Though he did manage to last two whole series, or sixteen years, in the job.
Ian Levine has taken a break from calling people liars and then changing his mind over those 90 missing episodes to claim that Nikki Wilson is in line for the job. Which suggests that either (a) Moffat's a big fan of TSJA (after already picking up Brian Minchin) or (b) she's a hottie.
