10 Movie Secrets That Were Hiding In Plain Sight

7. Luke's Projection Didn't Leave Footprints - The Last Jedi

With the full might of the First Order facing down on him, everything was set for the confrontation between Luke and Kylo Ren in The Last Jedi to be highlight everyone had waited for. Everything was in place, except for one tiny detail: Luke wasn't actually there.

While it's obvious in hindsight - I mean, how did Luke have time to get a fresh trim, dye his beard and craft a new lightsaber while the fate of the galaxy was hanging in the balance? - there is one key detail that makes this even clearer.

The surface of the planet they're on is initially white salt, which turns into a dark red when anyone touches it. Consequently, the pristine surface is two completely different colours by the time Luke turns up to the battle, however he doesn't seem to be able to impact it.

Multiple times we see him walking on the salt without leaving any footprints, while Kylo (and everyone else we've seen) does. Obviously, it's because he's not really there, something which everyone should have realised.
