While I mainly remember Donald Sutherland as Oddball in Kelly's Heroes, looking up his list of films reminds me of his appearance in the fun odd horror 'Dr Terror's House of Horrors' which has a loosely tied together set of horror stories; quite a fun film. I also see he had a part in 'Billion Dollar Brain', which I've not seen for ages.
