Rose McGowan guest-starred on Wednesday night's episode of "Law & Order: Special Victims Unit" that still has viewers buzzing a day later.

On the show, she played sexy bombshell Cassandra, who encounters detectives Benson and Stabler at a swinger's club and during a recent press event, McGowan revealed how she got "sucked into" watching the show and why she signed on for the role.

"My sister and I once got sucked into a ten hour marathon and watched an entire Saturday I was like, 'Dear God. And wow, what an amazing show,'" McGowan told reporters on a conference call last week. "But, because they've had amazing people in it, such as Maria Bello, Jeremy Irons, Marcia Gay Harden. I mean, just - they have had such an amazing lineup of people that go in and out of it."

She adds, "You know, if it hadn't been the case, I don't know that I would have been as attracted to it, but they get such powerful actors. And Mariska Hargitay and Chris Meloni are so good. So to be able to be in that world that I've lost many hours of my life to watching was definitely a treat."

As a fan, McGowan talked about her expectation of the show's sets and what they were like in reality.

"You go into the interrogation room and I was like, 'Oh, it's a lot bigger than it looks on television,' or it - and my sister, who's actually brilliant, but doesn't really know anything about the business, she asked who made the ['Law & Order' clang-clang] sound on the set," McGowan said. "I was like, 'No, no, they don't, but that would be pretty great if they did.'"

So is McGowan anything like the con-artist, seductive, bombshell she played on "Law & Order: SVU?"

"I would say there are actually no similarities in my personality or attitude, particularly with my character Cassandra, and that's what's delightful," the actress said. "I get to be me 24 hours a day, so I obviously jump at the chance to play something that is very, very different."

McGowan, 37, is known for her role in movies such as "Grindhouse" and "Planet Terror," as well as her work on the fantasy drama series "Charmed," which ended in 2006. Yet, despite her brief return to television, McGowan says she's not ready to return to a regular role full time.

"I was on "Charmed" for five years and it's a grind, and so I haven't been quite ready to go back to that yet," she said. "But, that's what's brilliant about this episode is I get to go in and work with some knockout actors and leave."
