10 Actors Who Had No Idea What Was Coming Next

10. Billy Boyd - The Fellowship Of The Ring

Despite it going on to become one of the most successful franchises in movie history and having a near $300 million budget in the end, Peter Jackson's The Lord of the Ring's trilogy still oddly possessed an independent movie spirit at heart.

And one of the finest and funniest examples of this free-spirited approach to working whilst putting these epics together comes in the shape of nobody telling Billy Boyd Gandalf's ridiculously explosive firework was legitimately going to blow during a famous early scene in The Fellowship of the Ring.

As Boyd and the rest of his Hobbit gang revealed during the DVD commentary for the flick, the actor playing Peregrin Took was under the impression that the actual explosion would be added in later via digital effects. So, when the time came to shoot the hilarious back-and-forth between himself and Dominic Monaghan, the panicked scream we hear burst out of the actor was very much genuine.

So was the urine trickling down his leg, earning himself the charming moniker of "p*ssy legs" from his co-star for his troubles.
