I'd be very disappointed if a Serenity edit used scenes from Firefly given the leap in production design etc between the two, but I guess that's the editor's decision. I really want to see a re-assembly of the version I saw in London on February 2005 - there were numerous little things that were cut for either keeping a PG-13 or to stop from boring newbies to the 'Verse, but that would have made it extra-sweet for established Browncoats. I'll try to find a proper list off the Serenity forum archives (I know there is one), but some of the most memorable were:
- Brief scene where the Operative is about to torture Minty and Fango.
- A longer shot of Kaylee crying over the dead child at the massacre.
- Mal and Inara nearly kissing after seeing the video message about the Reavers.
- There was a much more explicit low-angle shot of the Operative's sword being run through Mal (in the film it happens off-camera). Presumably cut for the PG-13, though it may have been because some though it would be "silly" that Mal would carry on after it. Maybe - I just thought it made him all the more hardcore :-D
- Fireworks in the funeral scene (hence why they're putting notes on a bloody rocket!!!)
- When Mal enters the cockpit in the final scene, he has a little play with Wash's dinosaurs and flicks the three switches before his scene with Wash.
