Youth culture giant Vice Media has joined with Magnolia Pictures to promote the June 12 release of “The Wolfpack,” which won the U.S. Documentary Grand Prize at the Sundance Film Festival.

Vice plans to launch an extensive transmedia cross-promotion and social-media outreach campaign to  capitalize on its following.

Crystal Moselle’s film follows the six Angulo brothers, nicknamed “the Wolfpack,” who have spent their entire lives locked away in their Manhattan apartment learning about the outside world through the films they watch obsessively and re-create. After one of the brothers escapes the confines of the apartment, the power dynamics in the house are transformed.

“Vice’s unparalleled ability to engage with young audiences makes them an ideal partner for promoting ‘The Wolfpack,'” said Magnolia president Eamonn Bowles.

The doc was produced by Moselle, Kotva Fims’ Izabella Tzenkova, Verisimilitude’s Hunter Gray and Alex Orlovsky. David Cross, Tyler Brodie, Louise Ingalls Sturges and Cameron Brodie exec produced.

Magnolia also released a trailer for “The Wolfpack” on Wednesday.
