Directed by: Tim Burton
Starring: Johnny Depp, Winona Ryder, Dianne Wiest, Anthony Michael Hall
Continuity mistake: When Kim is watching Edward cut the roses, in closeups she's quite close to the curtain, and it's hanging straight down. In the wide shot she's slightly further away, and the curtain is angled outwards because she's holding it back with her hand.
Visible crew/equipment: When the crazy woman who said that Edward comes from hell leaves the backyard, you can see the reflection of a crewmember on the left side of the window.
Officer Allen: We're looking for the man with the hands.
Answer: As the other response says, the number of years is never stated. Physically, I think he is supposed to look about twenty years old. Bill wants him to start a proper business. None of the adults seem to think that he should be in school.
