Only in Hollywood

For the week’s hot casting: G. Gordon Liddy and socialite (and aspiring actress and former pal of Sly Stallone) Cornelia Guest, signed for “The Squad,” a sexy action number from a pair of former porno makers known in the biz as the Dark Brothers.

According to director (and former Dark Bro) Greg Brown, ex-Watergate felon Liddy will play “a contemporary ex-L.A. police chief who runs for mayor, murders women and is a bondage and discipline freak.” Guest will be “an evil scientist, who’s a sex freak who manipulates peoples’ minds.”

And bodies. Guest will “install” mind control devices in LAPD cops that will lead them to become “overly aggressive and sexually insane.”

Brown, whose credits include “The Devil in Miss Jones III” and “New Wave Hookers,” teams with producer Walter Gernert (the other Bro).

Liddy--who said he’d once seen a Dark movie (only he can’t “remember it”)--noted, “I worked a lot for shady guys in Washington, D.C., so what do I care about these guys’ past careers?”

As for his first big-screen role--following playing heavies on “Miami Vice” and “Airwolf”: “I like the fact that this guy has no redeeming qualities. But he’s not Washington material. There’s no person as evil or degenerate as your average congressman.”

As for Guest: “I want to come across as a young, sexy lady, but I won’t do any sex scenes. Besides,” she quipped, “they (the film makers) know I’m sexy enough on my own.”
