Dwayne Johnson will play stuntman hiding dementia diagnosis

Dwayne Johnson is set to play a stuntman hiding a dementia diagnosis from those around him in a new action drama.

The WWE legend turned Hollywood megastar, also known as The Rock, has signed up to star in Free Byrd, which is the latest filming coming from Ben Affleck and Matt Damon's Artists Equity studio.

As reported by Variety, Johnson will place a Las Vegas motorcycle stuntman who is hiding his dementia diagnosis from everyone, including his mechanic brother, before one last risky jump.

The official logline teases that the movie "examines and confronts the mind’s vast mysteries and the beauty and power of asking for help before it’s too late".

In a statement, The Wrecking Machine star Johnson said: "Free Byrd is a gift in many ways.

“Emblematic of life’s sacred beauty, as well as life’s harsh and callous reality.

"The subject matter of Free Byrd has become deeply personal to Greg Kwedar and myself as we’ve started to unpack this fateful journey together."
