Two of Marvel's biggest stars, Avengers: Age of Ultron's Mark Ruffalo and Guardians of the Galaxy's Zoe Saldana, come together for an indie that doesn't require extensive makeup or motion capture work, in the first trailer for Infinitely Polar Bear. The plot is set in the late 1970s, following a manic-depressive mess of a father (Mark Ruffalo), who tries to win back his wife (Zoe Saldana) by attempting to take full responsibility of their two young, spirited daughters, who don't make the overwhelming task any easier.

Infinitely Polar Bear debuted at the 2014 Sundance Film Festival, where it was met with critical acclaim and eventually picked up by Sony Pictures Classics. Maya Forbes wrote the screenplay and makes her directorial debut, after writing movies such as Seeing Other People, The Rocker, Monsters Vs. Aliens, Diary of a Wimpy Kid: Dog Days and the upcoming Trolls. Bad Robot's J.J. Abrams and Bryan Burk also serve as executive producers.

The supporting cast is rounded out by newcomers Imogene Wolodarsky and Ashley Aufderheide, who play the young daughters, along with Keir Dullea, Wallace Wolodarsky and Mary O'Rourke. Take a look at the first footage from Infinitely Polar Bear, which arrives in theaters July 19 from Sony Pictures Classics. Will you head to your local theater to see Hulk and Gamora as two parents?
