With all eyes on Cannes this weekend, it was slow going for art house titles at the box office, with the slate of newcomers dominated by single-theater releases. The highest among these was IFC Films? ?Wakefield,? a drama starring Bryan Cranston and Jennifer Garner which made $14,120 from a single screen. Also getting a single-screen release this weekend was the PBS documentary ?Abacus: Small Enough to Jail.? Among holdovers, BH Tilt?s ?Lowriders? made $1.1 million from 365 screens in its second weekend for a per screen average of $3,183 and a cume of $4.19 million.
