As stated, Scott Wolf has mainly avoided nude scenes over the course of his career, but there are a couple worth noting. Wolf is credited as having a butt scene in 2019's Inside Game, but I didn't include it as I suspect it was a body double. There was something about the way it was filmed that had me wonder. I tried to find a source, and if I find out it's actually him, I'll add it for sure.
Teenage Bonnie and Klepto Clyde
'What starts out as teen rebellion for two minor hoods quickly turns deadly as the pair rob and kill their way to mythical status.'
To me, this mooning moment is really Wolf's only 'actual' nude scene, and as you can see, it's quick and dark. A year before Party of Five, Wolf appeared in 1993's Teenage Bonnie and Klepto Clyde. The film marked one of Wolf's only lead roles in a feature film, and to me, was one of his best. He's also really hot as Clyde.
The Evening Star
'Continuing the story of Aurora Greenway in her latter years. After the death of her daughter, Aurora struggled to keep her family together, but has one grandson in jail, a rebellious granddaughter, and another grandson living just above the poverty line'
I have not been able to bring myself to fully watch 1996's The Evening Star. Terms of Endearment didn't need a re-make, and this flick seemed a way to suck a little more $ out of the original and allow Shirley MacLaine to star along without that pesky and talented Debra Winger matching her beat by beat in every scene.
I have watched this scene however, more than a few times.. It's not really for the quarter inch of Wolf's butt that's quickly flashed, it's for his poses in his tighty whities. Wolf's character has dreams of being an underwear model, and wants to show Melanie, (Juliette Lewis) his poses.
