Jurassic Park (1993)

Corrected entry: When the T-Rex moves to Dr. Grant and the boy they hold still because it can't see things that don't move. Unfortunately though, T-Rex's have a highly developed sense of smell and would certainly have known they were there.

Correction: Considering the fact T-Rex's have been extinct for 65 million years, its quite difficult to tell what their sense of smell was like. Also, Grant says quite clearly in the film that sight was the Rex's most powerful sense and if you stayed still, it confuses him.

There is actually evidence that T-Rex had visual clarity 13 times better than a human, and could see objects up to 6 kilometres away. So, T-Rex would have been able to see Dr. Grant and the boy regardless of whether they moved or not.

If a T-Rex is unable to see something when something is standing still, it's not its most powerful sense. Smell makes more sense, but not provable.
