When a character tilts their head up and looks like a deer in head-lights, it means something pretty incredible has their complete and undivided attention. It could simply be the result of looking up at something so incredibly beautiful or unbelievable that the character can't help but stare, or there could be some element of mind control involved. Either way, the effect is the same - a character looks up and experiences a sense of wonder at what they are witnessing.
- The cover for 2001: A Space Odyssey featured Dave Bowman having this reaction to the monolith.
- The initial reaction to the aliens arriving in Independence Day of pretty much everyone who witnessed it.
- At the end of of The Great Dictator the awestruck upward look is combined with Psychic Link, when Hannah looks up and says "Listen", to the people around her, as the Jewish barber gives his Balcony Speech from a faraway location that none of them can hear.
