LaBeouf had been due to appear in the production alongside Alec Baldwin and Tom Sturridge, but producers confirmed in a statement yesterday that he has left just a month before the show is slated to open.
"Due to creative differences, the producers of Orphans and Shia LaBeouf will be parting ways and he will not be continuing with the production," the statement read. "An announcement on the replacement of the role of Treat will be made shortly."
Private emails shared by LaBeouf on his Twitter page appear to suggest that he clashed with Baldwin during rehearsals for the production.
The first, captioned "creative differences", featured LaBeouf musing on what it means to be a man and concluding: "Alec, Im sorry for my part of a dis-agreeable situation (sic)."
A reply, sent by someone named "Dan" - possibly director Dan Sullivan - said: "I'm too old for disagreeable situations. you're one hell of a great actor. Alec is who he is. you are who you are. you two are incompatible. I should have known it. this one will haunt me . you tried to warn me. you said you were a different breed . I didn't get it (sic)."
LaBeouf also uploaded a video apparently of his audition for Orphans and shared a second email which showed him and Baldwin making amends.
"I've been through this before," Baldwin said. "It's been a while. And perhaps some of the particulars are different. But it comes down to the fact that what we all do now is critical. Perhaps especially for you.
"When the change comes, how do we handle it, whether it be good or bad? What do we learn? I don't have an unkind word to say about you. You have my word."
LaBeouf replied: "Same. be well. good luck on the play. you'll be great."
LaBeouf also appeared to suggest that Sturridge was in no way responsible for his exit from the production, tweeting: "Depth of friendship does not depend on length of acquaintance. Tom = good dude - good actor."
He attached another email, this time from Sturridge, who wrote: "I don't really know what to write... I said my piece but they didn't really listen. I don't understand what has happened here. Maybe you have had a more enlightening conversation with someone by now. All I can say is that it truly was an honour to work with you even if it was only for a few days.
"I was stunned by the work you were doing, the performance you were giving. I think you lifted the play to a place higher than maybe it even deserved to be. I hope this isn't the last time we work together and I especially hope it isn't the last time we see each other. Hope you're ok brother."
News of LaBeouf's exit from Orphans comes shortly after the actor tweeted that he had put his hand "thru the door" at rehearsals. He also attached a screengrab of his apology to playwright Lyle Kessler, in which he wrote: "im a child, dont mind me."
Orphans is still due to open for previews on March 19, with opening night set for April 7.
