Dalton should have taken the role earlier, say in Octopussy or A View to a Kill. Licence to kill would have been his Swansong if it was his final film. It would not have stopped the legal trouble that followed though.
I truly believe that if LTK had been given a decent advertising campaign and released in the Autumn as opposed to the Summer it would have been more successful. The competition was to strong that season.
This artwork (not mine by the way) represents Licence To kill better than the original poster art.
