Some of history's greatest achievements were actually made by accident.
The microwave oven was invented by a man working on short wave radio. Penicillin was discovered after a scientist forgot to dispose of some bacteria. Chocolate ice cream was original conceived as a low-cost fuel for cars!
Okay, that last one was a lie, but wouldn't it be great if it were true?
The same principle can be applied to the world of film, as several iconic scenes from iconic movies contain big ol' whoopsies.
We've already covered ten of them, but it turns out that so many gaffes were left in the final cut that there's room for a whole new list.
A lot of these are down the actors involved being total pros and carrying on with a scene even when everything had gone completely out of shape. The sign of a good performer is one who is comfortable adlibbing when something goes wrong, and these ten guys and gals all proved their worth when the script went out the window.
So, next time you make a mistake, just remember, it could end up becoming legendary.
10. Jane Russell Takes A Dip - Gentlemen Prefer Blondes
From 1953 comes Gentlemen Prefer Blondes, a movie musical starring Marilyn Monroe and Jane Russell. If you've never heard of it, then you'll have at least heard of its most famous song - Diamonds Are a Girl's Best Friend.
If you haven't, then quite frankly what are you doing with your life.
Whilst Monroe has obviously gone on to achieve megastar status, at the time it was Russell who was the more accomplished performer. She lived up to her status as an icon when a scene by a swimming pool went horribly, hilariously wrong.
The closing sequence for the number Ain't There Anyone Here For Love involved several muscular men in tiny trunks leaping over Russell as she sat by the edge of the pool. Unfortunately for her, one of these hunks was a little too beefy, clipping the back of her head with his leg and sending her crashing into the pool.
Because Russell was an absolute pro, she carried on, emerging from the pool to finish the song. The blunder fit her character perfectly and is probably the best bit of the entire scene.
