London: Actress-filmmaker Angelina Jolie admits she and Brad Pitt deliberately "tested" their relationship by making "By the Sea" together, even though it was perhaps a big risk for them as a couple.
The 40-year-old star directed and starred in the drama with her husband, in which they played a rowing married couple, just weeks after they tied the knot in 2014.
Jolie said the couple always like putting themselves to such challenges, reported Female First.
"It was our way of testing ourselves. We knew that if we could get through this, we'd come out even stronger and happier. And we did. We've always liked putting ourselves through challenges, even though it was maybe a little more dangerous for us as a couple.
"I don't think we want to go through it again though." Jolie, who raises kids Maddox, 14, Pax, 12, Zahara, 11, Shiloh, nine, and seven-year-old twins Knox and Vivienne with her husband, found the first week of filming particularly difficult, until she and Brad had a frank conversation.
"The first week was the hardest because Brad knew I was worried and impatient. You don't want to drag your own personal issues into the process, but we had a talk and decided we were going to be completely honest with each other."
