Did i find a gaffe (or am i just looking too hard)? I am watching Godfather - in the first time we see Michael and Kay, Michael just arrived at Connie's wedding and is busy trying to eat - he is explaining Luca and Tom Hagen to Kay. Kay has a lit cigarette in her left hand - when the camera angle switches to showing both Kay and Michael, the cigarette is no longer there, but when it switches back to the shot from behind Kay the cigarette seems to magically appear. Did she just switch it and i miss it, or did i find my first gaffe?

(Forgive me if this has been discussed before - still relatively new to the board.)
