The Raid 2 and documentary Finding Vivian Maier found solid footing in their opens this weekend, while Cesar Chavez had a mixed start as holdover juggernaut The Grand Budapest Hotel continued to hold sway as March makes its exit. Sony Classics ventured into the action-thriller genre with The Raid 2 and scored a solid open. The feature by Gareth Evans, a follow-up to his 2012 pic The Raid: Redemption, grossed nearly $177K in just seven locations, by far taking the highest per-theater average of this weekend’s reporting newcomers with a solid $25,272. Raid: Redemption grossed nearly $214K when it opened in March 2012, averaging $15,270. It went on to cume over $4.1M domestically. “There’s a loyal following to the first film, but the word-of-mouth from all the screenings we’ve had have been great,” SPC co-president Michael Barker told me this week. “It was a triumph at Sundance and at SXSW. All these factors foreshadow a good run.” It will head into about 30 theaters in five or six cities this week before heading wide into 1,200 locations.
