He really took possession of the part, inflections, body language, singing, attitude and most importantly-- confidence.
Tim Curry landed the role of Dr. Frank N. Furter in the original 1973 London production of The Rocky Horror Show and later starred in the movie version entitled THE ROCKY HORROR PICTURE SHOW, which was his motion picture debut.
Rocky Horror, created by Richard O'Brien, the original Riff Raff, wrote the book, music and lyrics and calls it 'something any ten-year old could enjoy.' The stage production opened in London at the Royal Court's experimental Theatre Upstairs as a six-week workshop project in June, 1973. O'Brien said in an interview "I think I invested it with my psyche and that subliminally it feeds the audience psyche. It has a hypnotic hold, like a fairy tale invested with psychological tremors 'Daddy, won't you tell me the story again?'. You never tire of hearing the fairy story as a child and that's why you never tire of ROCKY."
