Mega Piranha

Mega Piranha (2010) is a creature-feature action movie you can watch online on iFILM. Eric Forsberg directs this Asylum-style sci-fi disaster romp starring Paul Logan, pop singer Tiffany and Barry Williams, set along Venezuela's Orinoco River.

A special-forces agent and a young scientist start digging into a string of deaths on the water. The cause is a gene experiment gone sideways: lab-bred piranhas have turned smart, fearless and impossible to stop, doubling in size with every meal. Soon a small school becomes bus-sized monsters that ram boats, launch themselves onto land and swarm whole cities.

This is gleeful low-budget trash, complete with goofy physics, fish used as missiles and a finale that throws logic overboard. Pick it up when you want loud and silly rather than scary. Stream Mega Piranha (2010) online on iFILM.
