Michael Phelps is very similar to Christopher Nolan's Batman. While Nolan's Bruce Wayne took a break from wearing the cape and cowl, Phelps dramatically decreased his training regiment and event program in comparison to his cult-like preparation for the Beijing Olympics.
If the 2000 Olympic was Phelps' League of Shadows era as a wide-eyed 14-year-old Olympian, the 2004 Olympic Games in which he won six golds and a pair of bronzes was the second half of Batman Begins.
Ultimately, the Beijing Olympics was Phelps' Dark Knight moment. Those 17 days in the pool were a flawless masterpiece for Phelps that could only be equalled, never surpassed and that launched Phelps into legend status.
Finally, Dark Knight Rises, which opened in theatres a week before the Opening Ceremonies is Nolan's conclusion.
Phelps has also chosen to leave the Olympic stage on top after the London Games.
"I knew that I wanted to swim for another four years after 2008. I don't have that feeling now," he said. "Sure, I am excited I'm at the Olympics and representing my country. I don't see myself going on. I just don't want to.
