Morgan Spurlock, the American documentary filmmaker, stepped down from his production company on Thursday, one day after he published a post saying that he had committed sexual misconduct in the past, including settling a harassment allegation and cheating on his wives and girlfriends.

An emailed statement from Warrior Poets, the independent production company that Mr. Spurlock co-founded, said that the decision was effective immediately, and that the company would be led by co-founder Jeremy Chilnick and another partner, Matthew Galkin. It did not give a reason and did not say whether his departure was permanent.

The announcement came after Mr. Spurlock posted a statement on Twitter late on Wednesday saying that as he was watching women publicly accuse high-profile men in a range of industries of sexual misconduct, it was “time for me to be truthful as well.”

“As I sit around watching hero after hero, man after man, fall at the realization of their past indiscretions, I don’t sit by and wonder “who will be next?” he wrote in the statement, which was linked to his verified Twitter account. “I wonder, ‘when will they come for me?’”
