The film features character actor Deezen in one of his few leading roles, as well as guest appearances from many veteran character actors known for their "tough guy" and gangster roles, including Mike Mazurki in his final screen appearance.
Don Anthony (William Hickey) is the head of California's largest crime family. Unbeknownst to him, his voluptuous mistress Gina (Morgan Fairchild) and his arch-rival Don Francisco (Stuart Whitman) have plotted a hostile takeover of the business, and Don Anthony is gunned down following a mob meeting. Lying mortally wounded in the hospital, Don Anthony directs his chief lieutenant Monk (Irwin Keyes) to locate his estranged son Tony to assume the family business and carry on the Anthony name.
Unfortunately for the family, Tony (Eddie Deezen) is a wimpy nerd with no idea of the true nature of his father's business. As Monk tries to transform the milquetoast geek into a fearsome gangster, Don Francisco attempts to overthrow him through Gina's powers of seduction, while a pair of bumbling hitmen (Brinke Stevens and Jack O'Halloran) try to bump Tony off at every turn.

The film starred Eddie Deezen who had previously worked with Fred Olen Ray on Beverly Hills Vamp. "I love Fred," said Deezen said the film was "so much fun to shoot. I had a ball. Morgan Fairchild, a lovely lady."
Professional reviews of Mob Boss were moderately negative. Entertainment Weekly gave the film a "C-" rating, writing "This mostly rotten comedy from bad-movie king Fred Olen Ray (Hollywood Chainsaw Hookers) offers amazingly low-brow slapstick, but the cast has fun (especially Morgan Fairchild, of all people) and the liberal use of boingy sound effects makes for a few silly laughs". Allmovie gave the film 1.5 out of 5 stars without a written review.
