This was the beginning of the prolific “bleach blonde with implants” portion of her career, which lasted from 1989 until she got the implants removed in 1998.
1989 – Cold Feet
1989 – High Stakes
1992 – Forever
1992 – In the Heat of Passion
The videos are here. The B films of that era have had a slow trek to HD. The Cold Feet videos are in 720p, the clips from In the Heat of Passion are from an upscaled VHS rip, and the vids from the other two films are from DVDs.

I think it’s virtually impossible to make a definitive nudography of Ms. Kirkland because she was just so prolific. There are some titles from different eras where she was reportedly nude too but they’re so obscure. She was reportedly nude in a bizarre counter culture film called Brand X (1970) during her artsy fartsy brunette era. Paint It Black (1989) was reportedly her first foray into erotic thriller genre during her the blonde MILF period. And she supposedly did a nude scene in something called Archaeology of a Woman (2012) during her granny phase.
I do respect that she went nude for so long, got an Oscar nomination, but instead of heading to “respectable” parts, doubled down on the nudity – the kind of career I wish Elizabeth Berkley had had, instead of getting blacklisted for her big nude lead role
