Ben Affleck
The 'Batman vs Superman: Dawn of Justice' star likes to have a constant reminder of his children - Violet, 10, Seraphina, seven, and Samuel, four - with him on set so he takes to displaying their work around his place.
Asked what he likes to keep in his trailer on set, he said: "[It's] mostly stuff from my kids. It's the only personal stuff I have - the drawings and art. It's a good place to hang up the latest artwork to come out of school."
And the 44-year-old actor also revealed he works hard to share the parental duties with his wife Jennifer Garner despite their split but admits homework isn't one of his strong points.
He added to Entertainment Tonight: "We do our best. We try our best ... My areas of expertise with the kids [are] spotty at best. Not homework. I only play an accountant in the movie. In real life, I'm badly wanting."
Meanwhile, Ben previously admitted he has felt "vulnerable" ever since he first became a father.
He said: "When you have kids, what's that expression, 'Your heart is outside your body,' all of the sudden you feel so vulnerable and this fear of a child being vulnerable is very very powerful.
"I face dilemmas that we all do everyday about what's the right way to raise children, what's the right thing to teach them? Every moment there comes a crossroad."
