Blink and you'd've missed it, but the first teaser trailer for Breaking Bad spin-off Better Call Saul has aired - and, understandably, it's been enough to send die-hard fans into raptures.

The nine-second clip, which previewed during an AMC Breaking Bad marathon in the States over the weekend, shows Bob Odenkirk - aka the titular Saul - telling an unnamed man in a bar why lawyers are like insurance.

While the clip - which has been blocked for copyright reasons in the UK - gives little away, there are a few things about the upcoming series we know.

Here are six to remember:

1. Better Call Saul is actually a prequel set in 2002, six years before Breaking Bad.

2. Saul isn't yet called Saul. He's known instead as Jimmy McGill.

3. Some familiar faces star - including Jonathan Banks as Mike Ehrmantraut. (Yay.)

4. Walter White won't feature. Co-creator Peter Gould has hinted that the series will include flash forwards, though - and Bryan Cranston will direct an episode.

5. It's due to air in the US in early 2015. The UK release date is TBC.

6. Season one will comprise of ten episodes; season two has already been commissioned.

Get. Excited.
