Jessica Biel has signed on to star opposite Adam Sandler and Kevin James in Universal Pictures' "I Now Pronounce You Chuck and Larry." Dennis Dugan is directing the comedy, which is being produced by Shady Acres and Happy Madison.

"Chuck" revolves around two heterosexual firefighters (Sandler and James) who pose as a gay married couple in order to qualify for their department's domestic-partner benefits. Biel will play an attorney who reps the duo in their case and ends up being the object of Sandler's affection.

The comedy has an Aug. 31 start date.

Dugan, who directed the comedies "The Benchwarmers," "Big Daddy" and "Happy Gilmore," replaced David Dobkin, who dropped out over creative differences. Dugan is repped by UTA, manager Eric Gold and attorney Jason Sloane.

Biel next stars in "The Illusionist," with Ed Norton and Paul Giamatti. The movie opens wide Aug. 18. She recently wrapped filming on Sony's "Next," with Nicolas Cage and Julianne Moore.

Biel is repped by CAA, Management 360 and Jackoway Tyerman Wertheimer Austen Mandelbaum & Morris.
