Karen Allen
Nude

Though she derives the most professional satisfaction from her extensive work in live theater and is acclaimed as a gutsy, risk-taking actress, slinky brunette minx Karen Allen will forever be known to skin-chasers as the cheating sweetheart of Animal House (1978). Who can forget those big, flashing green eyes, so innocent and easy to trust? And the smile, slightly crooked, totally endearing, flashing like a promise of never-ending delights. And then the full view of her ass, its smile every inch as winning as the one on her face. Who cares if she smiles exactly the same way at a ton of other guys? We next caught her grinning in A Small Circle of Friends (1980), where she showed her small circles of areola in an open blouse. Four years later, Karen smiled harder than ever in Until September (1984). Her eyes are still big, and her boobies are still mobile and high as she straddles her man in a girl-on-top tussle. Bask in the warmth of her grinning buns as she lounges belly down in bed, then walks her happy-face rear across the room. Karen became a skinternational skinsation when she flashed her undies in the Spielberg blockbuster Raiders of the Lost Ark (1981). As spunky “Marion Ravenwood,” she made us shoot spunk out of our raging wood. We hope Karen’s nudity didn’t backfire in Backfire (1988), as this was the final time she appeared nude on screen. She’s still acting, though, and played Marion Ravenwood once again in Indiana Jones and the Kingdom of the Crystal Skull (2008).
