10 WTF Animal Horror Movies You Won't Believe Exist

10. Birdemic: Shock And Terror

Alfred Hitchcock’s classic 1963 horror The Birds taught us that our feathered friends can actually be pretty damn terrifying when they turn against you and anyone who’s attempted to eat fish and chips al fresco in a seaside town can tell you an irate and hungry seagull can often be more terrifying than a rabid dog.

But the birds of Birdemic: Shock and Terror (two emotions you won’t be left feeling after seeing the movie) aren’t using their beaks and claws to attack humans, but acidic spittle and the ability to dive-bomb and explode on impact – defences they’ve developed in response to global warming or something equally inconceivable.

It’s inspired by Hitchcock’s masterpiece, believe it or not, but even though there’s half a decade separating the two movies and leaps and bounds in terms of visual effects, it’s The Birds that emerges the more technically realistic whereas Birdemic’s avian villains look like they’re superimposed during post-production using Microsoft Paint.
