No, this is not the recent Western fronted by Idris Elba. It’s a 1956 boxing movie with Humphrey Bogart.
The Harder They Fall was Bogart’s final film role. He was diagnosed with cancer shortly before production, but kept this secret from his fellow cast.
The movie is a noir-ish critique of the boxing industry, especially ‘fixed’ fights. It also stars Rod Steiger and, in a smaller role, Max Baer, who was the world heavyweight champion in 1934-35.
This is the rare US one-sheet poster, which I sold recently, with mixed emotions. Its a simple but very powerful design. I hope the buyer got it framed and up on his wall, it certainly deserves it.
