Better Call Saul will be teased through its very own music on Sunday at 7:15pm, midway through the finale of AMC's Breaking Bad marathon.

This is very exciting news – thus far we've been drip fed teasers no longer than about 10 to 15 seconds, whereas this "music video" could well be two minutes plus.

It was co-written by co-creators Vince Gilligan and Peter Gould and composed by Dave Porter (he did that iconic Breaking Bad opening theme).

This won't be the first time Vince has used music videos in a cinematic way, with Breaking Bad having featured 'Negro Y Azul: The Ballad of Heisenberg' along with Jesse, Badger and Skinny Pete's band Twaughthammer's 'Fallacies'.

The theme song for Better Call Saul, which arrives on AMC and Netflix early next year, is performed by country singer Junior Brown.

The last teaser we saw from the show saw Saul in court for the first time.

Bob Odenkirk (Saul) and Jonathan Banks (Mike Ehrmantraut) will return for the prequel, but don't expect to see Walt and Jesse.
