Previews began Nov. 23. The cast features Jeremy Piven — of "Entourage" and "Ellen" fame — Keri Russell, Andrew McCarthy and Ashlie Atkinson. Fat Pig is directed by Jo Bonney (Fifth of July, Stop Kiss, Living Out).

Piven plays a youngish big city businessman who unexpectedly finds himself attracted to an outgoing, overweight librarian. The relationship furnishes him with feelings of contentment and growing maturity, but causes him unending and increasing anxiety at work, where the prying and judgemental minds of his co-workers prove merciless in their assessment of his new mate.

Relative newcomer Atkinson is Helen, the object of Piven's affections. McCarthy is Carter, a rotter of an office pal, and Russell is Jeannie, Piven's spiteful ex-girlfriend.

Fat Pig marks the stage debut for Russell, who is best known for her work as Felicity Porter on the TV series "Felicity." Film star Andrew McCarthy was seen on Broadway in The Boys of Winter and Side Man.

LaBute's other plays include bash, The Shape of Things and The Mercy Seat.
