Naked H50

I'm curious ... which H50 actors have appeared in films or TV shows (though I doubt the latter) naked?

One is Kathy Beller (S08E11, The Waterfront Steal) in the movie The Betsy ... full-frontal nudity!

Sam Melville (S01E03, Tiger By The Tail; S02E21, Most Likely To Murder; S04E08, For A Million ... Why Not?) appeared in the 1966 flick A Smell of Honey, a Swallow of Brine which I saw once. It had naked characters in it and Melville didn't appear under his real name. The description of this film at IMDb says: "A young woman teases, seduces, and emotionally destroys young men for her own twisted enjoyment."
