When I heard that Han Solo was in Joss Whedon’s short-lived but nerd-adored “Firefly,” I was like, “No kidding? Where?” And Geek With Curves was all, “look just above Mal’s [Nathan Fillion's] left shoulder.” And I was like, “Where? I don’t see Han Solo.” As it turns out, what I needed to be looking for was a small replica of Han Solo frozen in Carbonite.
[It] was brought on set since Nathan Fillion is such a huge Star Wars fan. The props team joked around and added it to sets whenever they could, it apparently became a running joke. It didn’t get grabbed out of every scene before shooting though. [Geek With Curves]
There are more examples in the slides that follow. You’ll have to enjoy them without me, as this post exceeds my FDA-recommended exposure to geeky crap for the week. If anyone needs me, I’ll be doing pull-ups and listening to AC/DC.
