William Sasso has landed a role in New Line’s comedy “Dairy Queens.”

Story is about an overbearing mother who will stop at nothing to ensure that her daughter wins a teen beauty contest.

Pic stars Kirstin Dunst, Kirstie Alley, Ellen Barkin and Denise Richards.

Sasso will play Hank, a mildly retarded nudist who runs his family’s hardware store.

Michael Patrick Jann is helming from a script by Lona Williams; Judy Hofflund and Gavin Polone are producing, with shooting is slated to begin Aug. 2 in Minnesota.

Sasso (“Happy Gilmore”) is currently a regular on Fox’s “Mad TV.”

Jeff Goldberg of Agency for the Performing Arts and Danielle Galiana-Allman of Allman Talent negotiated the deal for Sasso.
