If we're allowed to pick holes in "Lord of the Rings", "The Hobbit" and "Indiana Jones", then we can't let the "Harry Potter" series get away with anything. We're sorry. In our defense, they only have themselves to blame. Harry is forever being told, all the way through all the films, that he has his mother's eyes. They're particularly memorable eyes, too, being a vivid shade of green. So this mistake makes no sense.
When we eventually see Harry's mother Lilly, in flashback scenes in the final film, guess what's wrong? The actor playing the part doesn't have green eyes, but brown. Lots of girls have green eyes. That requirement should have been front and center on the list of what was needed at the casting stage. How did they manage to get this so wrong? And why did nobody realize?
