Jack Weston practically steals the whole movie
The entire cast was terrific but Weston had a flashy part and he soared with it. McQueen must have liked him because Weston found his way into 2 other McQueen films, The Cincinnati Kid and The Thomas Crown Affair.
It would have been fun to see the 2 of them starring in a buddy movie sometime. Alas.
