Oh, come on. Those paparazzi have special lenses on their cameras and other tricks which could make ANYBODY look bad. You have to admit,
I doubt if it occurs often enough for the cliche to be true, but another example would be Lysette Anthony – she played the beautiful young princess in Krull, then couldn’t get a lot of other roles because she’d been typecast. She wound up getting naked and doing it softcore style in erotic thrillers like “Save Me” and “A Brilliant Disguise.”
Looks like she’s doing more mainstream stuff now.
Ah.
Gillian Anderson. Unworthy thoughts abound, and hey, the X-Files ain’t cutting those big checks anymore…
Then why does her filmography on that very same page unaccountably fail to list these porno movies? So she did a couple of erotic thrillers - big whoop. If that was a criterion for inclusion we’d need to name every B-list actress in the business.
Naomi Watts, Kate Beckinsale, Jessica Alba, Jennifer Lopez (if only for her butt!), Verona feldbusch (because I’m curious)…
The relatively impressive thing about Tanya Roberts is that, after Charlie’s Angels, she was forced into the softcore trenches. . . and then years later still managed to land a role on a popular sitcom (That 70’s Show). My guess is that’s not too common.
I believe the “Hot Line” series in Roberts’ filmography was a series of softcore porn vignettes with Roberts as the host. Don’t know if Roberts actually participated in the sex, but it was certainly all about the sex.
Drea DeMatteo. There’s just something about her.
Actually, I want them do porn and have their careers to go very well. So, I guess my answer is none.
Except Janeane Garafolo. I’d like for her to disappear for ever, along with all record of her existence. But, that’s just IMO, of course.
I can’t believe that no one has said Bea Arthur or Mary Tyler Moore yet.
Are the still alive?
Most notoriously, Dana Plato. She didn’t go for all-out hardcore but she definitely ended up in the Skinemax ghetto.
Stephen Geoffreys, aka Evil Ed from Fright Night, got out of mainstream movies and had (maybe still has, for all I know) a successful career in hardcore gay porn.
Well, there are a lot of hot porn actresses already out there, so if Britney wasn’t famous and was in porn, no-one would bat an eyelid. It’s becuse she’s famous we want her to do porn I think.
I’ve seen waaay too much porn in my life and have become quite bored with it, but I still hunt out the sex scenes with famous people in it, not because they’re so much hotter than porn actresses, but because they’re famous.
How did I let this one slip by? Please tell more (but obviously don’t link).
Oh, and actresses I want to see do porn, Eliza Dushku.
Jamie Lee Curtis, if only to answer the traditional question.
no mention of Allyson Hannigan yet?
Janeane Garafolo. Yum!
I can’t believe that no one has yet posted either Kate Hudson or Liv Tyler. Together. Doing Elisha Cuthbert. In a Jello pit. While Alicia Silverstone looks on. I mean, it’s just so obvious. The plot practically writes itself.
Brittany Spears’ career is nearly over. She’s resorting to staging two-day marriages and “accidental” nipple slips to keep herself in the news.
Within a year, she’ll be in a skin flick. You’ll see.
Phyllis George… although I’m fairly certain more than a career tank would be required.
Melissa Joan Hart.
Or, barring that, Amy Lee from Evanescence. 
The little blonde cocktail waitress/surfer chick on North Shore. Please…
Oh yeah, and Don Knotts.
I’d like to see Valerie Bertinelli in a porn.
