In the scene at the club when Prince
and Kristin are outside dancing, there's an enormous protrusion from his pants that's only visible at one particular moment. I'm not 100 percent certain it isn't just a lighting accident, but it sure looks like he's "excited" beyond his diminutive frame. Whenever I point this out to people, they always say, "wow! I didn't notice that the first time through", so I thought it might be interesting.
