This is the right place to post this!
I’d also be curious to here about your ideas for having Han and Luke talk to each other.
I cut a good portion of the conversation between Han and Finn and Rey during their flight to Maz’s and used the remainder of the footage of Han. Particularly Han saying “Luke” for when Luke enters the MF and then “Let’s see what you got” for a shot counter shot conversation between Han and Luke. Luke saying 'nothing you say can make me change my mind", followed by Han’s “Let’s see what you got” then R2 plays the hologram, implying he is talking to R2.
It doesn’t good great rn, but after some color corrections and polishing it may look ok. The problem is I have only scratched the surface of what premiere is capable of.
