Chris Pratt says his premature baby boy brought him closer to his wife, Anna Faris.

The 'Guardians of the Galaxy' star and the 37-year-old actress welcomed their son, Jack, into the world nine weeks early in August 2012 and the now 23-month-old tot was forced to spend the first month of his life in an intensive care unit in hospital, but the 35-year-old actor says the experience helped them realise that being successful isn't the most important thing in life.

He told PEOPLE magazine: "It brought me closer to my family and it restored my faith in God, not that it needed to be restored, but it really redefined it. It showed me who in my life is really close to me."

He added: "[At first] our number one priority was attempting to conquer this town [Hollywood] as actors and we supported each other in our quests. Now with a kid, our priority list has shifted, and he's at the top of it."

Chris is besotted with his son and tries to spend as much time as possible with him.

He said: "He's so open and there's no fear in him no matter what. He is so charming that my plan is to just let him take care of us as soon as he is old enough."
