HOLLYWOOD, CAMarvin Solis, director of the late-night Cinemax offering Uptown Girl, nabbed the coveted Best Skinematography trophy at the 2004 Eroty Awards Monday night. 'It's truly an honor to be recognized for this wonderful project,' Solis said of the 43-minute erotic thriller, which stars Kira Jackson as a bored high-society housewife seduced into the steamy world of underground sex clubs. 'I couldn't have done it without the help of my location scout, my lighting coordinator, and all those 14-year-old Cinemax viewers.' Last year, Solis won the Zalman King Lifetime Achievement Award.
