The Whistler (2010)

Cannes, the French Riviera. Armand Teillard is happy with life; a busy store downtown, a delightful girlfriend, a magnificent record collection and lunch every day at Sofia and Martial's family restaurant with a perfect sea view. So when Sofia tells Armand that Zapetti, a property developer with mafia connections, is putting the squeeze on her to sell up, he is horrified. Armand is an easy-going guy, but when he gets mad... actually, Armand never gets mad. He leaves that to his twin brother, Maurice, The Whistler. When Maurice rides into town in his Aston Martin and designer suit, Zapetti, his mob and the corrupt local politicians are in trouble. But what if, behind the dyed hair and tinted contact lenses, Maurice and Armand are one and the same guy? Is Cannes big enough for the both of them?

Unfortunately the movie The Whistler is not yet available on HBO Max.
