Better Call Saul has debuted its first teaser trailer during AMC's Breaking Bad binge, a 9-second clip showing a younger Saul Goodman trying to talk round a client and confirming the show's February 2015 air date.

The TV spot is the first proper clip we have seen from the spin-off prequel, albeit an upsettingly short one, and was snuck into AMC's Breaking Bad marathon showing over the weekend.

"Lawyers? We're like health insurance, you hope you never need it but man oh man, not having it? No!" Saul is seen telling an unknown character in a bar, sporting a fuller head of hair than usual.

Better Call Saul will find the crooked lawyer going under the name James M. McGill, an Irish identity he used before switching to a name more suitable "for the homeboys".

A billboard advertising McGill's services popped up in Albuquerque recently where the series is filming, with the phone number on it, quite delightfully, actually working.

AMC previously promised that the Breaking Bad spin-off was coming in the first quarter of 2015, but this teaser confirms that February will see its arrival, with Netflix expected to follow soon after.

Season 1 will consist of 10 episodes, with a second season already having been commissioned with 13.

Bryan Cranston recently revealed that he will direct an episode of the show, but ruled out any kind of return for Walter White.

"I think it was on the Ashley Banfield show on CNN, and she brought up the speculation," he said of his previous "never say never" ruling. "I was just toying with her and said, “I don’t know!” which created a whole brushfire of rumor.

"I don’t think that we’re going to see any kind of rebirth of that show, or that character," he added.
