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, reported Ace Showbiz.
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 US on June 19.
