The problem here is that Scaramanga is the mirror image of the wrong Bond...“You get as much pleasure out of killing as I do, so why don’t you admit it?” Scaramanga goads Bond at one point — the moment that it becomes clear to the audience that this Bond villain has arrived at least two movies too late (or five movies too early).
As 'Renard The Anarachist', he's the kind of crook they just never had in previous Bond movies—a bad ass. Keep your Dr. Evil clones, keep your evil Rupert Murdoch clones, this guy just wants to be a nasty prick. He's Scottish, nasty is what they do. And Bobby Carlyle can do nasty, just ask anyone who saw Trainspotting or Ravenous. But Carlyle, admittedly, is all wrong for this movie. He's a cockroach in a humungous bowl of fruit.

It’s the Colin Baker syndrome; the television is almost too small to contain an actor of that magnitude. Shove him on stage or in a big budget movie of the same story and Whitsun-Jones would prosper... When he is pouring over his vision of a new Solos, it should have been an insanely sized globe that he could enthuse over like Nero before the burning of Rome, but instead he can be seen staring down at the equivalent of a stress ball on his desk. When he grabs a gun in episode five and starts firing like a madman, it should have been a sub-automatic machine gun causing endless destruction, not a dozy BBC prop that goes 'phut'.
