Daryl Roth, who produced Pulitzer Prize-winning plays Three Tall Women, Wit, Proof, Anna in the Tropics and The Goat, or, Who Is Sylvia?, is the picture's producer with Richard Guay, co-producer of "Kinsey."

Joining Roth and Guay as producers is Starec Productions. "A Very Serious Person" was filmed entirely in the greater New York area. The original screenplay was co-written by Busch and Carl Andress. In the film, "Busch plays Jan, a male nurse whose new patient (Polly Bergen) has been raising her orphaned grandson Gil (Verhoest)," according to production notes. "The three spend a memorable summer by the seashore in which they form the nucleus of an unusual extended family, and Gil takes his first funny, traumatic steps toward adulthood."

Daryl Roth and Charles Busch's professional collaboration began with Busch's comedy The Tale of the Allergist's Wife. Roth was one of the producers who brought it to Broadway from Manhattan Theatre Club. The hit ran ran for nearly two years and launched a national tour.

Most recently, Roth produced "The Lady in Question is Charles Busch," a feature-length documentary on Busch's life and career which has already been seen at the Tribeca Film Festival, L.A.'s Outfest, New York's The New Festival, and many others.

Smith Cameron starred in the plays Fuddy Meers and As Bees in Honey Drown, and will soon be co-starring with Anna Paquin in Kenneth Lonergan's film "Margaret."
