We all love watching stunts. Sometimes, when we're so engrossed in the epicness of the film we're watching, we barely give a second thought to the amount of time, hard-work and effort that goes into creating them.
For 99% of the stunts we see, everything went without a hitch thanks to the incredibly talented and self-sacrificing people that work in movie stunt co-ordination.
On the odd occasion, though, things go horribly wrong. And when the stakes are so high - high speeds, big heights, high danger - the consequences are often disastrous.
Take a look below to see 5 stunts that went very badly awry.
Harry Potter And the Deathly Hallows: Part 1
If you had to think of the most dangerous stunts that have been pulled off over the years, Harry Potter And The Deathly Hallows Part 1 probably wouldn't be the first off your lips.
But for David Holmes, one of Harry's (Daniel Radcliffe) stunt doubles, it's a project he will never forget.
Whilst filming one of the quidditch scenes in which Harry of his team fly around on broomsticks, Holmes was accidentally slammed through the air into a set wall, before falling on to the crash mat below.
Holmes told the Daily Mirror:
‘My stunt co-ordinator grabbed my hand and said, "Squeeze my fingers" I could move my arm to grab his hand but I couldn’t squeeze his fingers.'
Holmes was rushed to the nearest hospital where doctors told him he would be paralysed from the chest down, with only limited movement in his arms.
The Lord of the Rings: The Two Towers
Not only was Viggo Mortensen a complete badass as Aragorn in The Lord of the Rings, he was also a complete badass on set.
Mortensen insisted on doing all of his stunts. To the extent that he broke two toes and a tooth in the process. It's rumoured that Mortensen had the tooth repaired whilst the crew had lunch only to continue filming in the afternoon!
Director Peter Jackson named him 'the walking wounded’.
Batman: The Dark Knight
The sad and untimely death of Heath Ledger wasn't the only tragedy to hit the set of Batman: The Dark Night.
Special effects technician, Conway Wickliffe, was killed during one of the film's car chase scenes. Wickliffe was hanging out of the window of the camera truck when the vehicle hit a tree at 20mph.
The adrenaline-packed XXX's endearing silliness was so awesome, in no small part, because of the film's high quality stunts.
We owe it to the film crew's talent and dedication for these incredible stunts, and nobody more so than stunt man Harry O'Connor.
O'Connor was being pulled at high speed on a paraglider when he hit a pillar of a bridge. He died on the spot due to heavy injuries.
The Twilight Zone
One of the most infamous accidents in film-making history was the tragedy that occurred on the set of The Twilight Zone.
A helicopter that was being flown with proper safety precautions crashed into the sea and took the lives of 3 actors.
A video, which is widely available available on the internet but I would advise against watching it, shows a section of helicopter exploding before the aircraft crashes to floor. Vic Morrow and two child actors, aged 6 and 7, were killed.
