It's not a Futura nor even a Gibson.  The body shape is very similar to the Gibson Explorer, which was the follow-up the the failed Futura, but the headstock is all wrong and the neck has only 21 frets (almost all Gibsons, including both the Explorer and Futura, have 22 frets).  The headstock's closer to a Fender Strat.  Considering how old this clip probably is, it's likely a custom-made model.
