The Off Broadway production of “Tribes” has recouped its capitalization costs, according to producers.News comes about a month before the drama by Nina Raines is set to shutter. Production began perfs at the Barrow Street Theater on Feb. 16. Production comes from Scott Morfee, Jean Doumanian and Tom Wirtshafter, who have made a habit of producing shows that carve out a relatively long commercial life Off Broadway. Their staging of “Our Town,” also at the Barrow Street, ran for 18 months starting in February 2009. That production also managed to recoup its costs, which can be difficult for Off Broadway shows given the limited ticket inventory of smaller venues, as well as the marketing challenges of competing with Rialto ad budgets. Producers didn’t specify the capitalization cost of “Tribes,” but in general, shows can be capitalized Off Broadway for a fraction of a Main Stem pricetag. According to producers, the six-character “Tribes” has grossed a total of $2.5 million so far. It closes on Jan. 6.
