Although most will remember him from CHARIOTS OF FIRE, I remember his from his one season stint as Barnabas in the early 90s revival of DARK SHADOWS. He was an exceptional actor that was, sadly, caught between the time of "movie actors just don't make TV" and "a move to TV means you just can't make it as a 'real' actor".
I knew him originally as Abrahams in Chariots of Fire. But then many years passed and then I learned his face anew as the nu-Sarek in nu-Trek. Then I watched Chariots of Fire not too long ago and then pieced it all together in my mind (also noting that the Borg Queen was in Chariots of Fire...) Kind of the Abrahams Sarek in the Abrams Trek.
Quite a few of the Chariots of Fire cast are now dead, sadly.
