I have a few ideas in mind my self and I would like to encourage some ideas here for fleshing out the important moments of The PT for insertion as flash back story across the OT.

Your idea must include where it goes in the OT footage and what scene / scenes you use from the PT.

And any subsequent alterations made to either the scenes present or later on in the film because of the added story element.

Here is an example.

Bens Hut in Star Wars A New Hope

Luke Mentors Luke about his Father and talks about the light sabre.

After the scene is finished it would cut to an edited version of the Duel with Qui-gon & Obi-wan vs Maul and No Anakin.

Qui-gon Dies and Obi-wan defeats Maul (Edited to be more like the OT)

The scene will end with Qui-gon asking Obi-wan that he "train the Boy"

Resume Footage

I'll single out a few that I think are perhaps important and rough placement

Birth of Siblings Luke (named) Leia (unamed) ESB there is another
Ben Delievering Luke to the Lars Homestead ESB there is another
Obiwan Talking to Anakin on Mustafa ESB Falcon Jumps away
Obi-wan Defeating Anakin on Mustafa ESB Falcom Jumps away
Anakin and Obi-wan rowing over Palpatine ANH After / nefore Destruction of alderan
Anakin trying to save Palpatine Mace Windu killed ROTJ ?
Anakin on the Operating Table becoming Vader ROTJ Luke captured
Anakin talking with Sideous about Dart PLaguiues. ROTJ

I am not very fond of the PT but I am trying to find a use for this back story and if possible make something for fun at the moment.
