DreamWorks has acquired the pitch "Substitute Husband" from scribe Michelle McGrath and actor Hayes MacArthur.
Plot details for the high-concept comedy are being kept under wraps. There are no producers yet attached to the project.
McGrath's credits include the screenplay "Chip on the Old Block," which she sold to Universal. She also penned a draft of "Lights Out" for Paramount.
She is repped by UTA, Benderspink and attorney Howard Abramson.
Hayes, who was recently cast in Warner Bros.' "Life as We Know It," will next be seen in the DreamWorks comedy "She's Out of My League," opposite Jay Baruchel. His TV credits include "How I Met Your Mother," "Pushing Daisies" and "Entourage."
