I think he was an English stage actor, wasn’t he? I remember seeing him playing a Roman emperor in some bizarre B-movie or other. Hold on…
Huh. Sad to hear he’s dead. 
Worked for Olivier, though; impressive.
Anyway, it was the Martyrdom of St. Sebastian, with, of all people, Michael Biehn as the saint. Screen caps look way gayer than I recall, but really I should’ve expected that. (warning: some of the screen caps linked elsewhere on that site are NSFW)
