Something to pay attention to next time you watch the movie. I don't know why I noticed this, but having worked in television in the past, I'm weird about paying close attention to things. In the scene where Paul catches "the big one" and takes a swim down the river. Pay close attention to the fish as he is holding it at shoulder height. I think this may be the first ever stunt double fish, LOL. When the camera angle switches from a frontal view to a rear view, the trout changes. In fact it switches a few times. One fish has a protruding lower jaw with a black tip. the other looks like a large hatchery trout, lower jaw shrinks. Different coloring too I believe. I'm sure the idea was to use 2 fish to shoot the scene multiple times so as to not stress any one trout. I'm assuming the editor of the film was NOT a fisherman! LOL
