We all love a cameo – they're the little Easter eggs we didn't know we needed.
But sometimes, they're so random that they make you rewind, just to double-check your eyes aren't deceiving you. So tell us, what's the most random, unexpected cameo you've seen?
Were you shocked to see Madonna confront James Bond in Die Another Day?
Perhaps you were surprised to see cameo king Stan Lee show his face in The Princess Diaries 2, of all films.
Or maybe, like me, you can't get over the fact that Cate Blanchett was in Hot Fuzz for about 20 seconds.
