Oh, the magic of editing.

True story: I loved the movie Cocktail with Tom Cruise. I set out to learn all his bar tricks from the film, including lighting a match with one hand. Took me two months and many burned fingers before I mastered it. Then, I re-watched the movie to make sure I was doing it right, only to realize it was an editing trick and he never really did it. Oh well. I learned a skill for life.
