Continuity mistake: At the end of the movie the daughter hands Harry a stem of flowers. The flowers have small daisy like heads. However, when the shot changes to show Harry holding the stem, it is very different. There are less flowers on the stem and the petals are larger.

Civilian: Are you crazy? Do you know how much I paid for this gun?
