The Main Chance is a 1964 British second feature ('B')[1] film directed by John Knight and starring Grégoire Aslan, Edward De Souza and Tracy Reed.
Criminal mastermind Potter needs a plane to smuggling jewels out of France, and sends his mistress Christine to recruit Michael Blake.
Potter radios Blake who is in mid-flight, telling him his plane is rigged with explosives which he will detonate by wireless.
The Monthly Film Bulletin wrote: "A neatly constructed tale of dishonour among thieves, with one comparative novelty in that nobody is killed or arrested.
Grégoire Aslan's philosophic Potter and Edward De Souza's Blake – who comes over as a cross between John Bentley and the young George Sanders – between them project a coolly refreshing air of cynicism.
