Liev Schreiber has revealed his children went on playdates with Angelina Jolie's kids while the two actors filmed action movie 'Salt'.

The actor - who has two children, three-year-old Alexander and 19-month-old Samuel Kai, with his partner Naomi Watts - explained that while he and Angelina shot fight scenes in a New York studio their kids took part in waterfights outside in the studio lot.

He said: "There were playdates which were amazingly fun! We were playing shoot ups inside the studio, and [our kids] were having squirt gun fights out in the lot."

The 42-year-old star revealed that his children and Angelina's brood with Brad Pitt - adopted trio Maddox, Zahara, and Pax and biological kids Shiloh and twins Knox and Vivienne - had a great time and "everyone got along".

Liev insists he and Angelina bonded over their children.

He said: "I think we're both in that place with our kids where they're really amazing, right around three-years-old, when all the language starts to come out of them. It's a very exciting period in someone's life, both the child's and the parents, and it was fun to bond over that."

Liev also praised Angelina for being so hard working on set.

He revealed her most admirable trait was "her diligence... and her commitment to the job. She works her butt off."

He added: "I was very impressed with how normal she was, and how easy she was to work with."
