It's barely anything, Teacake. Arnie gets a bit of a wang-wiggle going on in a single shot as he walks towards the punks at the beginning of the film. I really don't get the point of the comparison, but no mind.
Oh because I couldn't find it. This is like when someone told me Scott Bakula was in Playgirl and I hunted that thing down, must hate taken at least 3 minutes of my life, and he has a freaking speedo on. And Timewalker I would have been watching Australian tv which pretty much shows anything and everything.
If that's the reason (or should that be "if they're the reasons"?), then keep Stewart wearing pants. I've read his nickname was "Tripod." And was that really him "naked" in the Cardassian torture scene? I recall we saw a very naked hip (so no covering there).
To me what's really annoying in Voyager is how people (mostly B'elanna) always say "what's that supposed to mean?" when they perceive some kind of insult. Which seems to happen a lot...
The standard practice for such shots is for the actor to wear a special sock tucked over the, er, body part in question, so that they're not completely naked on set but when the camera shoots them from behind it looks like they are. Protecting the actor's modesty while still keeping the reality of the moment in terms of what the camera sees. Perhaps the question ought to be what size sock it was?
