Burly, ruddy-faced Irish actor Niall MacGinnis looked as though he'd be well suited for an alley fight, but most of his film and stage roles were of an intellectual bent. Active on stage with the Old Vic, MacGinnis made his first film in 1935. For many film buffs, MacGinnis' fame rests on two dymamic leading roles. He portrayed the crafty black-arts practitioner (based on Alisteir Crowley) who falls victim to his own deviltry in the 1958 chiller Night of the Demon. And, as every Lutheran who ever attended a church-basement "movie night" well knows, Niall MacGinnis essayed the title role in the 1953 film Martin Luther.
