Better Call Saul will have a flexible timeline, which opens up the opportunity for Breaking Bad characters to feature in the spinoff show.
Executive producer Peter Gould revealed that the show will feature scenes that jump back and forth across several decades.
He told the New York Daily News: "One of the great things about having a timeline which is flexible is that perhaps some of it takes place before Breaking Bad, during Breaking Bad, and after Breaking Bad.
"That gives us the ability to bring back characters that were killed on Breaking Bad."
Although Gould would like to see Bryan Cranston return as Walter White in the spinoff, he said he wants the show to "stand on its own".
He explained: "We think we have a story that is worth making. We could never dream of the kind of success that Breaking Bad had and the love we got from the fans. But [with Saul] at a certain point you have to do the best job you can and tell the best story that entertains you, get a good response and hope people like it."
Better Call Saul stars Bob Odenkirk as crooked lawyer Saul Goodman. It has already been granted a second season by AMC, before the first season has even aired.
The first, 10-part season of Better Call Saul began filming in New Mexico last month and will air in early 2015. The newly confirmed, 13-part second season will debut in early 2016.
