28 minutes in the movie, Gerard Butler and Billy Connolly both undress completely to go swim in the ocean. As they run naked we see their penises flopping around and then their butts. The scene is not very long but it is very clear. Both have good-sized uncut penises. Gerard Butler has a nicer butt as he is younger.

Will Young, openly gay, is briefly seen completely naked around 40 minutes in the movie. We see his big ass, and although he is sideways, we can clearly see he has a very large and long uncut dick. We will hopefully get to see more of naked Will Young soon.
