Marriage isn't important: Jessica Chastain

Los Angeles: Jessica Chastain, who is dating longtime partner Gian Luca Passi de Preposulo, says marriage is not a priority in her life.

The 'A Most Violent Year' star said she is fantastic in her three year old relationship, reported People magazine.

"I'm not quite sure of what I want in my life, and who knows if marriage is a part of it. So to me, marriage is not an important thing," she said.

The star ? who appeared in four movies last year, including the sci-fi blockbuster Interstellar ? is earning critical raves as a steely wife in the crime drama 'A Most Violent Year'.

In one memorable scene, she defies an investigator with the toss of a cigarette.

"That was a Chastain invention. I had no idea people would be coming up to me and flicking a cigarette and quoting my line, 'This was very disrespectful.' It's very cool," she added.
