I don't go see movies in the theater very often, but the past few movies I've seen in the theater, I've had an odd experience.
Example 1: Last December, I went to see The Holiday with some girl friends (it's a chick flick - w/ Kate Winselt, Cameron Diaz, Jude Law, etc.). We weren't too far into the movie when all of a sudden (to my great surprise) - John Krasinski shows up on screen! (If you don't know who that is, he plays Jim on The Office.) Well, I got excited and said to my friend Kara, "I did NOT know he was in this movie!" As it turns out, he was only in one scene. I looked for him the rest of the movie, but he wasn't there. (Sadness.)
Example 2: This week, I finally made it to see Dreamgirls (I like a good musical, and it was a childhood ambition of mine to be a backup singer in a girls group). It was a pretty fast-paced movie - we're going through decades and singing and having fun. Then, over 2/3rds of the way through the movie - "Wait a second. What is Jim doing in THIS movie??" He was playing some artsy/hippie assistant to John Lithgow in one scene. I don't think he had any lines - but I don't really remember because I was so surprised that he was in Dreamgirls. Is it just me, or does that not make any sense?!? I was just waiting for him to look directly into the camera and make a goofy face (probably referring to Beyonce's outfit).
So, I'm thinking, what other current movies could Jim show up in? At this point, not much would surprise me.
