Armie Hammer is exiting his planned action-comedy Shotgun Wedding after alleged graphic social media messages detailing his private life were leaked.

His part in the Lionsgate film, which is set to star Jennifer Lopez, will be recast.

In a statement obtained by PEOPLE, the actor said, "I'm not responding to these bull— claims but in light of the vicious and spurious online attacks against me, I cannot in good conscience now leave my children for 4 months to shoot a film in the Dominican Republic."

"Lionsgate is supporting me in this and I'm grateful to them for that," he concluded.

A production spokesman tells PEOPLE, "Given the imminent start date of Shotgun Wedding, Armie has requested to step away from the film and we support him in his decision."

Hammer's departure comes after several alleged messages were leaked by the anonymous social media account, House of Effie, according to Page Six. The messages, which have not been verified, are alleged to be from the Call Me By Your Name actor and depict sexual fantasies including rape and cannibalism.

he 34-year-old “Call Me by Your Name” actor previously described himself as a “dominant lover” who enjoyed “grabbing women by the neck and hair” during sex. Marrying now-estranged wife Elizabeth Chambers, however, changed his tastes.

“I liked the grabbing of the neck and the hair and all that. But then you get married and your sexual appetites change,” he told Playboy in 2013. “And I mean that for the better — it’s not like I’m suffering in any way. But you can’t really pull your wife’s hair.
