Got 24 seconds to spare? If not, make yourself 24 seconds to spare and watch this - you won't regret it.
Have a good oul gawk at Robert De Niro swanning around an auditions room, inexplicably turning around in circles and clearly getting dizzy in the process as he auditions for a part the part of Sonny in The Godfather. That's right, Sonny, the eldest Corleone son who was eventually memorably played on screen by the inimitable James Caan.
Obviously, Bobby De Niro did not get the part although the casting agents must have seen something in the confident (to say the least) actor. He of course won his first Oscar for playing a young Vito Corleone in The Godfather Part II.
Take a look at the scene as it played out in the actual film and let us know, would you have swapped Caan with De Niro?
