I object to the self-congratulatory Trivia listing in IMDb for Cash Markman, citing his status as the most prolific screenwriter in film history (NOT, he's prolific in porn video history, little to do with film), BUT this 1986 XXXer is one of my all-time favorites in the adult genre. I saw the video in 1986, so I can't do it justice in any blow-by-blow recounting of plot (excuse my pun), but suffice it to say that Keisha is given one of her best roles, and treated to very attractive styling/makeup, in this office comedy. Markman's script was genuinely funny, and I watched many of his subsequent offerings for that reason: I would recommend Butts Motel and When Larry Ate Sally (love that title) for starters.
Seems a shame, judging from the endless IMDb list, that he never got a shot at writing a mainstream project, but instead turned director, cranking out endless porn. I guess it falls under the heading of that old joke that ends with the punch line: "What!...and give up show business?".
