Watertight Doors closed BEFORE Collision in film

Dan Kappes

In this film, Murdoch orders the watertight doors closed moments BEFORE the Titanic hits the iceberg.

It seems to me that this film is implying that Murdoch realized the Titanic was too close to avoid the iceberg and that the collision was imminent and that he ordered the doors closed as a precaution.

But other Titanic films reflect what happened in real life, that the doors were closed immediately AFTER the collision.
