Vertigo?

The clue is really two clues in one, both referring to the title character in different ways.
no idea but will have a wild guess at
The pink panther
Not that one. Not many laughs in the film I am after.
Thomas crown affair
No. This film is British by a famous director who had a small but crucial role in the film.
Private Potter?
No. The legend in question is rather old.
Peeping Tom?
Well done, that’s the one. The film that finished Michael Powell’s career until he was rescued by Martin Scorsese in his old age.
OK, Thanks Devo. Next one:
Hate returns in rhythmic steps.
This film got a “Best Picture” nomination at the Oscars.
One of the two main stars of this film said it put an end to him being a “well known unknown” in Hollywood. The other won the Best Actor Oscar later in the decade this film was made.
Deliverance
Correct Devo
