As if anyone doubted it. Sharknado 5 is going to happen. 

According to the Syfy Network and The Asylum, Sharknado 5 started production Thursday in Bulgaria.

If filming is commencing in Europe, it means one thing: Sharknados are going global. The deadly weather phenomenon that features shark-filled twisters raining down terror on B- and C-list actors has spread to the Balkans, at least, and production will be in four additional countries. 

It makes sense. Really. 

The original Sharknado tore up Los Angeles. The second got up in New York's business. The third caused havoc from Washington, D.C. to Florida. The fourth went from Las Vegas to Niagara Falls, including a side stop in West Texas. 

In the closing scene of Sharknado: The 4th Awakens, the Eiffel Tower somehow crossed the Atlantic and plopped on Niagara Falls. Don't ask. 

Ian Ziering and Tara Reid will reprise their roles as shark-fighting heroes Fin Shepard and April Wexler. In addition, original cast member Cassie Scerbo will return as Nova, the bartender-turned-shark fighter.

Also, to retain its artistic integrity, Anthony C. Ferrante returns as director. 

No word on whether Cody Linley, a Lewisville native, will be back as Shepard's son, Matt. Dallas Mavericks owner Mark Cuban, who played the U.S. president in one sequel, said he doubts that he'll be cast. "Haven't heard a word," he said. 

Last year, Linley speculated on another sequel and whether he would be Sharknado's next action hero. 

"Somebody else mentioned that in another interview," he said. "I'm not opposed to it because I'm sure there will be a Sharknado 5." 

And sure enough. However, the announcement did not mention the subtitle or air date. 

Sharknado 4 got a 1-star rating and 18 percent rating on Rotten Tomatoes. It also registered the weakest ratings in the franchise since the first film. According to The Nielsen Co., Sharknado 4 drew a 0.8 rating in adults 18-49 with 2.77 million viewers, down from 0.9 and 2.8 million.
