SIN SCRIPT...To Barry King, TV meant Torrid Vice. And he took 10 percent of the passion earnings of some of the world's lushest and loose-moralled wantons--while his own acting talents brought him a return of a lot more than 10 percent on the flesh market. Life was an orgy of booze and babes--from the whip-hungry Karen to the double-feature delights of lust twins Lila and Lola. The script called for passion at high pay, with all the stops pulled out for a cast debauched and degraded, and Barry had it geared for wide-screen lust.
