Glass Or No Glass
Of all the errors in Titanic, this is the one that gets the most attention. That’s probably because it’s the most obvious of mistakes, other than the massive door that Rose hogged up all to herself. The error comes when Rose breaks the glass to get the fireman’s axe. She takes care to remove all of the glass from the frame after breaking it. But then, when she grabs the axe, we see that most of the glass is back. It’s a simple oversight but one that many viewers have clung to and mocked.
