This is a movie from [at least] 1976 and such.  It is the 
BEHIND the SCENES of making ANH back when it was simply known as Star Wars.  
What makes it epic?
It names names, as in labeling people to show who all these legendary FX folks are. 
It shows kit bashing in progress.  As Neo may say, "Whoah."
It shows testing out the starfield (breathtaking). 
It shows the Death Star surface being cast.
It shows rotoscope testing. 
Check out the couches in the viewing room.
The "trench run" as you've never seen it before.
It shows the 
pre CU   pre nge   pre Blu-Ray version of-  Er, nevermind...
Here you have it!
