I might be a total dork, but these Empire Strikes Back photos backstage are seriously cool.  This one was my favorite, largely because you can read the expression on everyone’s face:

Hamill: “What am I even doing here? I’m giddy!”

Ford: “The lighting intern is pretty hot.  Someone get me her name.”

Fisher: “If someone gets me a Martini, I’ll perform whatever sexual act they want.”

Lucas: “Where’s my neck?”
