Glass or no glass?
Though there are many such mistakes in Titanic (which we will talk about later), this is by far the largest and most noticeable. We are referring to Rose’s attempt to release Jack when, while searching an emergency glass plane, she finds an axe and breaks the glass to retrieve the flaming axe. The glass comes out almost completely.
However, as she goes for the axe in the following scene, the majority of the glass is strangely still in the case. How is that possible? Well, observant viewers paid close notice to this small error.
