6. The throwback cameos
Sharknado 2: The Second One's plot takes a backseat to the mountains of cameos in the film. It might seem like a hodgepodge of people, but some of the best cameos are nostalgic candy: Downtown Julie Brown, Biz Markie, Sandy "Pepa" Denton (with Salt nowhere to be found). A personal favorite was Robert Hays as the pilot of the ill-fated flight at the start of the film--you might recognize him from his role as a pilot in another amazing film, Airplane!
5. The not-so-throwback cameos
I can imagine that many actors wouldn't be caught dead starring in a movie called Sharknado. After the first one's success, it seems like everyone and their mother was now lining up for a chance to be a part of the franchise. Be on the lookout for appearances (and ridiculous death scenes) from Kelly Osbourne, Perez Hilton, Subway's Jared Fogle, Andy Dick, and more.
