Sharknado has descended on Orlando.

Filming for the third installment of the 'Sharknado' cable-television movies has begun this week at the Universal Orlando Resort and will continue into next week.

Locals have been cast as theme park patrons and soldiers.

Like the two previous Syfy Channel films, the cast includes Tara Reid and Ian Ziering.

The very much tongue-in-cheek disaster films follow the heroes as they do battle with shark-raining tornadoes.
