The very first scene of Dark City
shows Rufus Sewell climbing out of a bathtub and walking away from the camera nekkid as a jaybird. Jon, I didn't see anything at all wrong with his body.
He didn't look stocky or too broad. Looks are no problem, but I thought his voice was a little light, and I don't think it was the role. Not much resonance there.
I liked this movie better on second viewing. I think I must have been half-asleep the first time I watched; I didn't even remember that William Hurt and Ian Richardson were in the cast.
