Murder at Monte Carlo is a British 1934 mystery crime thriller film directed by Ralph Ince and starring Errol Flynn, Eve Gray, Paul Graetz and Molly Lamont, the production was Flynn's debut film in a lead role in England.

[3] A Fleet Street reporter (Errol Flynn) investigates the claim of Dr Becker, a professor of mathematics, to possess an infallible system of beating the roulette wheel at Monte Carlo.

[5] Flynn had been discovered by Irving Asher, the Managing Director of the studios, who put him under a seven-year option contract after cabling his head office in Hollywood: "He is the best picture bet we have ever seen.

He is twenty-five, Irish, looks like a cross between Charles Farrell and George Brent, same type and build, excellent actor, champion boxer & swimmer, guarantee he's a real find".

According to Filmink magazine: It was pretty impressive of Flynn to have bagged another movie lead but it must be remembered this was the era of wet fish British leading men – Barry Barnes, Leslie Banks, etc – and Flynn would have stood out among the alternatives on offer; he had the smooth appearance and cultured voice so beloved by British producers of the time, but he also had an athletic, virile appearance… Also, it was a cheap movie – they weren’t taking that much of a risk giving him a chance.
