As a storyteller, Vince Gilligan can't be accused of playing it safe.

The season 4 finale of 'Breaking Bad' contained several shocking developments bound to keep fans talking all week.

The creator of the AMC show addresses those events in depth below, and he also talks about the upcoming final season of the drama and whether it will air over one year or two. (By the way, my interview with 'Breaking Bad' actor Giancarlo Esposito -- a.k.a. Gus Fring -- is here, and my review of the finale is here.)

Since he arrived on 'Breaking Bad,' Gustavo Fring has been a memorable foil for Walter White.

Walter White is often reactive and scrambling to keep up with events, but Gus Fring is cool, collected and composed. The yin and yang between the two men -- one chafing at authority, one effortlessly exuding an air of command -- has provided the AMC drama with some of its finest moments.

In the interview below, actor Giancarlo Esposito talks about playing one of television's most charismatic characters, and about the events of 'Breaking Bad's' season finale.

Don't read on unless you've seen 'Face Off,' the final episode of 'Breaking Bad's' stellar fourth season. And be sure to check out my review of the finale and my post-finale interview with 'Breaking Bad' creator Vince Gilligan.
