Dwayne Johnson has credited film producer Beau Flynn as ''one of the most successful'' filmmakers in America.

The 44-year-old actor - who is also known as The Rock when he was a professional wrestler - has gushed about the creative mastermind, who Dwayne has worked on movies including 'San Andreas', 'Hercules' and 'Baywatch' with , on social media to mark his birthday.

The muscular hunk shared a picture of him with Beau on the set of the 2014 action film, which saw Dwayne play the lead role as the son of Zeus, on his Instagram account.

He captioned the picture: ''TBT from the massive destroyed set of #HERCULES in Budapest and HAPPY BIRTHDAY to my producing partner Beau Flynn of @flynnpictureco. We made a pact years ago to build big business and make global movies that impact and entertain audiences around the world. From JOURNEY 2: MYSTERIOUS ISLAND to HERCULES to SAN ANDREAS to BAYWATCH to RAMPAGE to SKYSCRAPER to many more big ones we're developing and announcing soon.

''Beau's one of the most successful and sought after producers in Hollywood. (sic).''

And the 'Moana' star believes Beau's ''filmmaking acumen, storytelling and killer instinct'' and his ''class, poise and integrity'', which Dwayne thinks is a ''rare combo'', is what has made him an ''A-list producer''.

He continued: ''As an A-list producer he brings additive value to every studio partnership with his filmmaking acumen, storytelling and killer instinct. But what sets him apart from the pack is he achieves global success with class, poise and integrity. Very rare combo in our business.

He's a good man who puts in the hard work daily to take care of his family and serve our global audience.

Bottom line: he's an a**hole, but it's his birthday and I gotta play nice.
