I would have preferred something a little more grounded: Hmmm, how about a little boy from a broken home raised by his mother and two sisters. The only father figure he has is a desperate coach who sees his chance for fame and accomplishment if only he can domesticate this prodigy and produce an Olympian. But wait, the boy has ADDHD and lots of angst... Oh, we saw that movie. It was called the "Michael Phelps Story."
From the Hollywood Reporter:
Beached centers on a chubby 4-year-old child who falls overboard during a family outing, is raised by whales and goes on to become an Olympic swimmer. (No, it’s not the Ryan Lochte story.)
