Well, this truly is the worst episode of Baywatch that has aired yet. It's one of those things you should put in the background while doing something else, if you really must watch it.
The episode is having tough time concentrating on what it really wants. First it's about a producer working on her actor, then it shifts to Mitch being offered a role on the movie, which includes all of his lifeguards going crazy to help him out, then the chick comes on to Mitch and he realizes he can't act. Meanwhile, the animal stuff was also quite a weird story. Sure, it led into the bikini contest, but overall it didn't do much because Harvey kept overacting.
