This short video shows some clips of actor Bradley Cooper performing and recording the voice of Rocket Racoon: "Bradley Cooper as Rocket Raccoon - Marvel's Guardians of the Galaxy Blu-ray Featurette Clip 4" (from the YouTube channel Marvel Entertainment).
In one shot you can briefly see in the background the words:
Groot woozily comes to his feet
PROPERTY OF MARVEL
which are displayed on a monitor that looks like it is showing a (poor quality) clip of the movie, presumably this is what the actors use to sync their lines with the action.
What is the significance of the word "SKYWALKER"?
