Sundance Selects has closed a deal to acquire North American rights to Nick Ryan’s K2 documentary “The Summit,” the distributor has confirmed to Variety.Deal was in the high six/low seven figure range according to a source familiar with the negotiations, and no release date has been decided yet. Lionsgate was among the buyers circling the title, and while some may question why the high-profile distributor were turned down, sellers were set on a theatrical release and the company refused to commit to one. CNN Films was also aggressive in chasing the pic, and others in the mix included Samuel Goldwyn Films and Magnolia Pictures. “The Summit,” which premiered Friday night at the Egyptian Theater, is part of Sundance’s World Cinema Documentary Competition lineup. Pic follows 24 mountain climbers up K2, one of the most dangerous mountains in the world. 48 hours after they set out for the summit, 11 of them have been killed or vanished. Submarine Entertainment negotiated the deal on behalf of the filmmakers. It’s the second straight deal in as many days for Submarine, which sold “Twenty Feet From Stardom” to Radius-TWC on Friday. A sister label to IFC Films and IFC Midnight, Sundance Selects is owned by AMC Networks.
