Dudley Moore
From Tardis Wiki, the free Doctor Who reference
Dudley Moore starred in Santa Claus: The Movie, a guilty-pleasure film for Shona McCullough, which featured Santa Claus and his elves. Shona's affection for the movie inspired the existence of Ian and Wolf inside the shared dreamscape in which Shona and others were plunged by the dream crabs, as Santa eventually revealed to Ian.
