After an hour of talking sharks, wetsuits and Phelps, instead of racing an actual shark, which I get can be dangerous, Phelps raced a CGI recreation of a shark, that ran the race separately. The two were then composited together, with the Olympic champion ending up 2 seconds slower than the predator.
I wasn’t impressed. It was more like Phelps vs. Shart, am I right? Other fans weren’t amused either.
