I get his ideological reason for 10 and out. That said if he gets the itch to makes more films please do. Its always a gift to see a QT film on the big screen.
Just direct more under a pseudonym. (I know the DGA doesn't allow it, but they used to)
i'd watch that but it might be a bit extreme/over the top for some unless he changes his style and at that point it doesn't make any sense. i want a bond with 10 minute dialogue and insane action sequences. would make the movies interesting. i like bond but it's dumbed down mindless shit now.
Maybe a documentary with all his regular actors and himself. They are not getting any younger, id like to see behind the scenes and interviews on set from his movies.
