Larry David’s Broadway play “Fish in the Dark” has officially recouped its startup costs, according to its producers, thereby turning the rest of the show’s sky-high take at box office into pure profit (minus the production’s weekly running costs).

Producers wouldn’t confirm a capitalization figure, but it’s not uncommon for a star-driven play with significant set demands and a large cast — such as “Fish in the Dark” — to land somewhere between $3 million and $4 million.

The recoupment will come as a surprise to exactly no one, given that the enthusiastic fanbase David has amassed from his work on TV’s “Seinfeld” and “Curb Your Enthusiasm” has endowed “Fish in the Dark” with blockbuster grosses since the play began performances.

David, making his Broadway debut both as a writer and an actor, leads a cast of 18 that also includes Rita Wilson, Rosie Perez, Jayne Houdyshell and Ben Shenkman. Directed by Anna D. Shapiro (“Of Mice and Men,” “August: Osage County”), the comedy centers on a death in the family.

The production’s stratospheric sales will certainly continue at least until David finishes up his run in the show June 7. It’s not yet certain whether grosses will remain as high when Jason Alexander replaces David in the lead role June 9, but Alexander’s links to David and to “Seinfeld” seem poised to keep audience interest high.

“Fish in the Dark” is currently scheduled to close July 19.
