The Moana star is producing and appearing in the comedy drama, based on the life of British WWE star Paige, and now he has added Vaughn to the cast.

Johnson, known during his WWE days as The Rock, announced the news to fans on Instagram, revealing the Wedding Crashers actor will portray a real-life washed up Eighties wrestler.

He did not reveal the exact identity of Vaughn's character, but described him as "a man who I know all too well and those of you who follow wrestling history know well too".

"The 80's wrestling star who squandered his money and opportunities because he didn't have the capacity to handle his fame," he added. "One bad decision after another, but these days he owns his past actions and does everything he can to give back to the wrestling business he loves."

Johnson went on to express his excitement at working alongside Vaughn again.

"Vince has been a buddy of mine for years and I'm fired up to see what he brings to this role," he gushed, before revealing cameras begin rolling on Wednesday (15Feb17).

He continued, "I grew up in and love this wild, crazy and unpredictable world of pro wrestling. Our little passion project is coming together nicely. More casting news to come. Production starts tomorrow. Let's shoot!"

Vaughn joins a cast which also includes Game of Thrones' Lena Headey and Shaun of the Dead's Nick Frost.

The project was inspired by U.K. TV documentary The Wrestlers: Fighting With My Family, about Paige and her family of grapplers, and will be written, directed and executive produced by The Office co-creator and star Stephen Merchant.

Fighting With My Family will be Merchant's first gig as a solo feature film director, after previously working with comedy partner Ricky Gervais on 2010's Cemetery Junction.
