Mark Ruffalo is a father of two girls who is also manic depressive in the trailer of "Infinitely Polar Bear". Arriving online on Thursday, February 20, the trailer sees Ruffalo's Cam struggling to take care of his children while his wife Maggie (Zoe Saldana) goes to a business school in New York, AceShowbiz reports.

The trailer opens with the first child narrating about Cam who was diagnosed with manic depressive in the '70s. He and Maggie met one day and she married him despite his eccentric behavior. Midway through the trailer, Cam is seen chasing his wife's car while professing his love. "That was so embarrassing," the girl says.

The trailer also sees Cam struggling with chores. "If you're not gonna do the dishes, then I am doing it," his second daughter says after seeing a mountain of dirty plates on the sink.

"Infinitely Polar Bear", written and directed by Maya Forbes, is inspired by the filmmaker's own father. It is set for release in the U.S. on June 19. "I wanted to show that a person's not defined by their mental illness, that's just a part of them," Forbes said at the 2014 Toronto International Film Festival, as quoted by Independent.

"We were on the same page," she added, referring to the "Foxcatcher" star. "We wanted it to be real but we wanted it to be funny and we wanted it to be sad. We wanted the whole range of life."
