|Alec Baldwin shoving a photographer in NYC|
Marcus told the New York Daily News newspaper: "He was looking mad. He said, 'Step back, step back.' I said, 'We're moving back.' "
According to the publication, Alec grabbed a second photographer, prompting Marcus to tell him to back off.
Marcus added: "I said, 'Don't touch him'. I knew he was going to attack me. I stepped back, and he kept coming.
"He comes after me, starts shoving and punching me - one time, right in the chin. And then he started shoving me, and pushing me. Then he goes the other way."
Fellow photographer Goran Veljic added: "He was like crazy, you know? There was an eruption of mad. ... You're going to get a marriage license, you should be happy. What happened with this guy?"
However, the 'Rock of Ages' actor had a different take on events, insisting he was "almost hit" by a waiting photographer.
He tweeted: "A 'photographer' almost hit me in the face with his camera this morning. #allpaparazzishouldbewaterboarded (sic)"
