3D Production company PassmoreLab has finished its filming for its latest science film “The Extreme Nature of Bats” after several months of filming at the Indian Ocean.

The film deals with the myths, truths and dark legends of bats. In order to make this possible, the crew went into a cave diving expedition to explore three bat species, the megabat, free-tailed bat and vampire bat.

Aside from their shoot at the Indian Ocean, the crew traveled to several parts of the world to film the bats in their natural habitats.

The production of the film started in October last year in Texas. The crew filmed the free-tailed bats at one of the state’s biggest caves. There are about 12 million Mexican free-tailed bats residing in the cave.

The crew then traveled to Romania to explore the myths of bats and the proceeded to Mexico to film the vampire bat and at the Indian Ocean for the megabat. Lets just hope the women wore sports bras on this epic adventure!!
