Bennett Miller’s ‘Foxcatcher’ portrays Olympic wrestler Mark Schultz as a brooding, nearly-mute mountain of frustration and rage. Based on the real Schultz’s last couple of days on social media, I’m going to say they got the anger part right. The mute stuff? Not so much.

After months of supporting ‘Foxcatcher,’ Schultz suddenly turned on the film, taking to both Facebook and Twitter to voice his disappointment with its portrayal of certain aspects of his life, from the way it presents his wrestling career to the suggestion that du Pont’s interest in Schultz may have been partly homosexual in nature. (This Facebook post lists what Schultz claims are a string of inaccuracies both big and small.) Via Variety, Schultz also posted that the film’s intimations that “there could have been a sexual relationship between duPont and I is a sickening and insulting lie ... after reading 3 or 4 reviews interpreting it sexually, and jeopardizing my legacy, they need to have a press conference to clear the air, or I will.”

Variety notes that Schultz posted an update to his tirade yesterday, one that apologizes for “the harshness of my language” but not for the comments themselves:

This battle between Schultz and Miller (who’s yet to publicly respond) highlights the dangers of biopics, particularly when their subjects are still alive. Everyone has their own version of the truth, and when it’s perceived that a film (particularly one that’s getting lot of publicity) doesn’t convey that truth, there can be backlash. What’s unusual in this case is that Schultz had been a vocal proponent of ‘Foxcatcher’ for months. He attended numerous screenings of the film, and praised Channing Tatum for the way he played him onscreen. It would seem that reading a couple of reviews changed his mind completely.

Schultz spokesperson told Variety that he’s “out of the country and unavailable for comment.” Wherever he is, he seems to have pretty good Internet access.
