Colleen Brennan debuted in softcore, then did porn from 1975-1987. "Not too pretty reddish blonde," writes Pat Riley in his X-Rated Videotape Star Index 2, "with a womanly body and medium to large tits. Sharon Kelly was the name used in early soft core such as Sassy Sue. Oyga Vault is from Raw Talent 2."

Trinity Brown "was my first major role," Brennan wrote on RAME 2/11/99, "[my] first time 'working' with all those guys, John Leslie, Jamie Gillis, and Joey Silvera. It was fun. I still remember a shot where John and I are in our cop car, (shooting without a permit to do so, of course), John turns on the flashing red light on the roof and off we went, turning the wrong way on a one-way street in downtown Los Angeles. Hey, it was FILM, it was EXPENSIVE, so we did the dialogue BEFORE we peed our pants! BTW, I thought the director, Robert McCallum, was top notch for the genre."
