Jessica Biel getting 'Engaged'

Actress attached to star in and produce raunchy comedy

Jessica Biel has signed up for some hard-core premarital nookie.

The actress is attached to star in and produce rookie screenwriter Julia Brownell's original screenplay "F***ing Engaged," a raunchy comedy about a couple who make a pact to have sex every day leading to their wedding so they don't turn into their crusty old parents.

Glen Basner and Aaron Ryder of sales-rep company FilmNation Entertainment ("The Road") are financing and producing.

Brownell developed the script with producers Dan Halsted ("Garden State") and Cameron Bunce, who got Biel and her Iron Ocean Films producing partner Michelle Purple interested. Halsted, Bunce and Purple also will produce.

It is the first script sale for Brownell, who is repped by CAA and Manage-Ment. A playwright from the MFA theater program at NYU's Tisch School of the Arts, she has written "Smart Cookie" and "Fantasy Baseball" for the stage and made the short films "Pizza Boy" and "The Assistant." She also has performed in improv and sketch-comedy groups.

Biel, repped by CAA and Management 360, most recently starred in "Powder Blue," "Easy Virtue" and "I Now Pronounce You Chuck & Larry." She next appears in "Nailed" and "Valentine's Day," hitting theaters in February.

Iron Ocean also is developing "The Devil and the Deep Blue Sea" and "How to Cook Your Daughter."
