Jennifer Garner says she embraced ''mom rage'' for her latest movie role.

The 46-year-old actress - who has kids Violet , 12, Seraphina, nine, and Samuel, six, with ex-husband Ben Affleck - plays a vengeful mother in her new drama movie 'Peppermint', and Jennifer has admitted she relied on some aspects of her real-life self for the role.

Appearing on 'Late Night With Seth Meyers', she explained: ''There's something about making this movie that plays out every bit of mom rage you've ever had on the playground or every bit of mom rage you've ever had, like, when your child is put in the back of a class and you feel they should be in the front. Or their feelings are hurt.''

However, Jennifer wouldn't encourage moviegoers to behave like her on-screen character, whose husband and daughter are killed in a drive-by shooting.

Jennifer's character subsequently dedicates herself to taking on the police and the criminals involved in the case.

The actress insisted: ''It is a fantasy. It's not a how-to video.''

Earlier this month, meanwhile, Jennifer revealed she loves ''backyard camping'' with her kids.

The Hollywood actress - who was married to Ben from 2005 until 2017 - bonds with her kids by sleeping out under the stars and cooking food on an open fire.

She said: ''I'm a big backyard camper. My kids and I camp in the backyard every year. We just spoke this morning about when we're going to do it.

''The only thing that matters is s'mores. Make whatever you want - hamburgers, eggs over the fire - but s'mores are all they'll remember. I like camping with a group of girlfriends too.''
