that's the problem no main characters but would serve meerly as classic star wars opening with a twist then transition to dagobah... Nothing explained, but would show the desperation in the fight against the empires tyranny.
The escape pod shot would be part the Tantive being captured and a modified version of the probe droids release from ESB opening.... flip em all to make it look more authentic. whilst using a shaking command deck shot, aboard the star destroyer with alarms along with the guy that does not shoot the escape pod from a new hope shooting a pod with CGI.
I'll always try to find an easier way before the suggestion new shots entrly btw
Oh and the escape pod should splash down into an ocean which would also help explain why they got away without having to say anything more about it.
it makes for an easy transition too. and easy to find footage for whilst not having to be descript.
kamino perhaps?
