Marilyn's first foray into legitimate acting was Jules Tasca's stage play Mind with the Dirty Man, which ran for 52 weeks at the Union Plaza in Las Vegas beginning in October 1974. At the time the play was the longest running in Vegas history. When it closed, Marilyn and the cast were honored with the key to the city.

Ron Pennington of The Hollywood Reporter wrote: "[Producer Maynard] Sloate's casting of Marilyn Chambers in the role of the son's porno-queen wife is especially ingenious and the actress makes a very promising stage debut here. Chambers, who projects an appealing stage presence, makes the role work surprisingly well... excellent."

Producer Maynard Sloate and Miss Chambers are feuding over the star's "sex-symbol" image. An "undress" rehearsal was held as Marilyn wants to appear (L) and as Sloate wants her to appear.
