11 Awesome Movie Scenes That Almost Didn't Happen

6. The Head - Jaws

Jaws is basically the archetypal example of how not to make a movie. Beset by production issues and the naivety of the film-maker, the shoot remarkably overran by more than 100 days, the sea made dependable shooting impossible and the infamously broken shark meant Steven Spielberg basically had to make the film on the fly.

It should have sunk to the ocean floor like a boat with a hole bitten out of it, which is a pretty professional segue into the key scene that almost didn't make it into the final film. If you were to ask people what traumatised them the most about Jaws, it's likely they'll either cite the first kill, Quint being bitten in half, the cage attack or - more than anything - Ben Gardner's head poking out of his wrecked hull.

Unthinkably, the best scare in the whole film wasn't even in the version that screened to test audiences and their lack of reactions made Spielberg go back and add it in. So you can thank those unphased guinea pigs for you having to change your underwear when you first watched it.
