All good things must come to an end, along with things that aren’t so good. The Sharknado series will have its final hurrah with the release of The Last Sharknado: It’s About Time appearing on SyFy on Sunday, and it’s going to get even more ridiculous.

As the sixth film in the series, The Last Sharknado picks up right after Sharknado 5: Global Swarming. Fin (Ian Ziering), April (Tara Reid), Skye (Vivica A. Fox), and Nova (Cassie Scerbo) go back in time to stop Sharknados in the past. The heroes will see the dinosaurs, participate in the Revolutionary War when sharks attack the US, go to medieval times when dragons and sharks mixed, and even venture into the future to fight robot sharks.

The first Sharknado came out in 2013 and was part of SyFy’s original films dealing with super-sized animals, which focused a lot on sharks. The movie became a cultural phenomenon with the plot of a tornado filled with sharks considered to be the quintessential “so bad it’s good” movie.

Along with the over-the-top schlock, the series has also been known for its mass amount of celebrity cameos including billionaire Mark Cuban, magicians Penn & Teller, legendary pro skater Tony Hawk, weatherman Al Roker, and even Game of Thrones author, George R. R. Martin. Making their first appearance in Sharknado 6 are astrophysicist Neil deGrasse Tyson, Twisted Sister frontman Dee Snider, LaToya Jackson from the famous musical family, and Alaska from RuPaul’s Drag Race.

The time-traveling nonsense of The Last Sharknado: It’s About Time starts at 8 p.m. Eastern Sunday on the SyFy channel. Only time will tell if this is truly the last Sharknado.

For those who want to see a movie about one shark that doesn’t need a tornado to cause terror, there’s The Meg out in theaters.
