The Germans - S1-E6
Corrected entry: When Basil goes from clapping his hands in the hotel reception area (just after the first hospital scene), he goes from standing completely still showing a clear 'action' cue.
Corrected entry: Ryan, the host, is played by Peter Cushing, who played Grand Moff (Governor) Tarkin, who commanded, and was destroyed with, the Death Star in Star Wars Episode IV: A New Hope (1977).
Correction: Pointing out that a well known, instantly recognisable actor whose name appears in the opening and closing credits appears in this episode is not trivia.
Correction: It's not hard to imagine that he walked in and took a moment to reflect that, finally, he has the run of the hotel to himself, then claps his hands eagerly and resumed walking.
