I have encoded the film as a radio wave which will eventually be received by a deep space probe and sent back so we can watch it. In between transmission and reception by the probe, I have destroyed all copies of the film.

Radio waves, happily, are not made of matter.

Finally a worthy post!

Hmm now there is a question of how broadly you use the adjective "physical". If you use "physical" on the highest level, i.e. an adjective pertaining to physics, then the copy would still be a physical copy since electromagnetic radiation is part of physics.
