Shia LaBeouf thinks Alec Baldwin may have got him fired from 'Orphans'.

The 'Transformers' actor exited the Broadway play after admitting he and his would-be co-star didn't connect as "men."

"I'm pretty passionate and impulsive, and he's a very passionate individual as well," LaBeouf told Late Show host David Letterman. "And I think that impulsiveness and that passion makes for, ya know, some fireworks."

"Me and Alec had tension as men. Not as artists but as men."

Letterman then asked if the '30 Rock' actor might have gotten LaBeouf fired.

"I think that might've been what happened," he said.

Despite the tensions between the actors, LaBeouf - who was seated on the front row for the first night of 'Orphans' - went on to praise Baldwin as "awesome."

Baldwin recently suggested that LaBeouf wasn't a true theatre actor and wouldn't have coped with the demands of a stage production.

Referring to one of the 'Lawless' star's tweets which read "The theatre belongs not to the great but to the brash," Baldwin said: "I can tell you that, in all honesty, I don't think he's in a good position to be giving interpretations of what the theatre is and what the theatre isn't.

"I mean, he was never in the theatre. He came into a rehearsal room for six or seven days.

"There are people who are film actors who have a great legacy in the theatre. Some of the greatest movie stars had really serious theatre careers and still do. And many film actors, though, who are purely film actors, they're kind of like celebrity chefs, you know what I mean? You hand them the ingredients, and they whip it up, and they cook it, and they put it on a plate, and they want a round of applause."
