Mark Schultz, whose life is dramatised in the Oscar-nominated movie Foxcatcher, has once again apologised for criticising the movie.

Foxcatcher chronicles Olympic wrestler Mark (Channing Tatum) and his brother Dave Schultz's (Mark Ruffalo) deteriorating partnership with philanthropist and coach John E du Pont (Steve Carell).

Schultz initially supported the movie publicly, only to later hit out at director Bennett Miller for crafting "complete fiction" with the character relationships.

The wrestler recanted his criticism over the weekend by insisting that he was "temporarily insane", and writing: "I apologise to you before the world Bennett. I'm sorry."

Schultz has now posted a series of messages on Twitter to accuse "writers" of turning him against Miller and Foxcatcher.

"The consensus is in. FOXCATCHER IS A MASTERPIECE," he tweeted over the weekend.

He continued: "I am praying so hard #Foxcatcher wins. Especially Bennett Miller, Steve Carell, and Mark Ruffalo.

"Thank you Bennett Miller for honouring my great brother Dave Schultz."

Miller was nominated for a Best Director Oscar for Foxcatcher last week, while Steve Carell was nominated for Best Actor.
