The key movie in terms of nudity with regard to Rider Strong is the 2001 indie
Buck Naked Arson [
Buck Naked Arson (2001) - IMDb], which has subsequently been given a more 'respectable' (i.e. dull) retitling for its release on DVD,
Eyes of Fire: Feel the Heat.
The first three sets of caps below are from that movie (although don't get too excited, because he doesn't show
everything).
I've also included a shot of his notoriously tufty pits from
Cabin Fever.
There's a further pic which purports to be of Rider Strong filed under "S" at stars masculines nues [
http://www.stars-masculines-nues.com/photos1.htm]. However, the origin of this image is the always-questionable site youngmalestars, and I personally consider it a fake. Furthermore, since I can't determine whether the person in it is over 18, I'm not linking to it directly.
