Jennifer Garner has received nothing but praise from her Miracles from Heaven costars despite the turmoil the actress was under during filming as a result of her split from estranged husband Ben Affleck.

The 43-year-old actress did not let her personal life interfere with her professional life even while film during the darkest days of their split, according to a report by People magazine.

“Jen, obviously, had a lot of personal stuff going on in her life,” said Martin Henderson, 41, who stars opposite of Garner in the film. “For her, things were a lot more complicated, so it would have been understandable if she brought a lot of that stuff onto the set. And not once did she ever, and once again I thought that just speaks to her character and how [incredibly focused] and professional she is.”

The film was under production last summer when news broke that she and Affleck were ending their 10-year marriage.

The end of her marriage “didn’t stop her ever from arriving on time and being a trouper and giving us the best performance in every scene and never talking about anything else other than concentrating and focusing on the role,” said director Patricia Riggen. “I have great respect for her.”

Henderson said he thought the emotional turmoil may have led Garner to dig even deeper to bring an extra quality to her performance.

“We all like to think we have that inner strength, and having known Jen a little bit she has that same quality,” said Henderson of Garner, who is mom to to Violet, 10, Seraphina, seven, and Samuel, four. “When you see her around her children, the commitment that she has, how seriously she takes the responsibility of a mother and how she puts her kids first over everything is quite rare. In that regard, I think Jen is perfectly cast.”
