Best or Most Accurate Representation

Of a UFO craft from cinema? I have two. One is the attacker craft from ID4. The manta ray ish disc. Jives with known photographs from 1947.

But to me the most accurate on screen UFO …

Flight of the Navigator.

Everything from its organic stream lined shape, like a silver eggish disc, down to its warp speed mode (tic tac looks like it elongates into a different shape in the Nimitz video before it takes off) and shape that evolves with its living metal skin, seems fairly accurate to real life accounts.
