PETER SARSGAARD and MAGGIE GYLLENHAAL

The engaged couple, who recently celebrated the birth of baby daughter RAMONA, really disliked each other's character on the set of the Sundance Film Festival-bound short film, in which they play a husband and wife.

Gyllenhaal explains, "It was actually pretty horrible, to be honest. He was playing a big jerk and it was hard for me to be around him when all day long.

"We were in a terrible relationship in the movie, and it was really sad to have to pretend to be in that relationship for four days.

"I love his acting and I would love to make many movies with him but I want to make sure that the making of the movie will be good for us, because I'm not sure that the making of High Falls was good for us."
