This trailer is the best possible way to tease the arrival of Better Call Saul, Season 3

Vince Gilligan is a genius.

How else do you explain his decision to tease the third series of one of the best TV spin-offs of all time by bringing back a major character from the original? Oh, and by making absolutely no mention of the show you're trying to promote either. That's Vince Gilligan, creator of 'Breaking Bad' and 'Better Call Saul', for you. If you had never seen Breaking Bad you would not have the faintest clue about the relevance of a 30-second TV ad for a chicken restaurant called Los Pollos Hermanos, but if - like us - you've watched it all then you'll greet the return of Gus Fring with much joy, and trepidation. https://www.youtube.com/watch?v=e_3WzxpdUc0&feature=youtu.be "As we know from Breaking Bad, Gus Fring is a man of great resources and is very much a long-term planner, and he has some very skilled and cold-blooded folks working for him," Gilligan said last year.

"It could have been through Gus Fring's agency, but not him personally.

"And furthermore, just because Fring's back - technically speaking, if not literally - it doesn't mean that folks should assume that they'll see him at the beginning of season three.

"This is a character who is very circumspect. Very cautious. He does not reveal himself easily.

"He makes people work to get to him, as we saw him make Walter White work very hard and jump through a great many hoops to get to face-to-face with him in Breaking Bad."
