Jennifer Garner said sorry for her acting being a "little off" the day after she agreed to divorce her ex-husband Ben Affleck

She was starring in the 2016 fantasy comedy 'Nine Lives' at the time the former couple were splitting, and its director Barry Sonnenfeld, 71, has now opened up about how she apologised for her performance on set being below par during her painful break-up.

He said in his new autobiography 'Best Possible Place, Worst Possible Time': "Jennifer Garner is a beautiful person inside and out. Any time she could, she'd fly back to Los Angeles where she was dealing with her husband, Ben, who was having issues.

"On her last day of filming, Jennifer was a little off. We were in a grand ballroom with hundreds of extras.

"I took her to the side of the room and asked if everything was OK. Behind her, in the distance, were hundreds of extras.

"She apologised for not being at her best. Ben and Jennifer had the night before decided to get a divorce.

"I burst into tears. 'It's OK, Barry. It's going to be OK', Jennifer promised. "'How could it be?' I wailed. 'Shhhhh. It's OK (Jennifer said.) It's going to be OK. It's for the best.'

"'I don't think so,' I howled."

'Nine Lives' saw Jennifer play Nina Brand, the wife of a businessman who has his mind trapped inside his daughter's cat.

'Men in Black' filmmaker Barry also said in his book he had a clash with Donald Trump on the set of a Macy's Christmas commercial he directed in 2009, which also starred Martha Stewart, Queen Latifah, Usher, Mariah Carey and Jessica Simpson.

He said Trump, 78, took issue with how he was filmed and demanded to be shot from his "good side".

Barry added the former US president stormed off the set after he told him: "Find a camera angle that shows my good side, or we're done here, because believe me, you're not shooting me from my bad side and if you can't do that, I'm leaving."
