The US actor will reprise his role as lawyer Saul Goodman in the hour-long new show from Vince Gilligan and Peter Gould.
"It's total drama, man," he told The Hollywood Reporter. "It's 85 per cent drama, 15 per cent comedy.
"One of the cool things about playing Saul now is that I get to have those moments [of depth]. I've certainly gotten a chance to dig deep in Better Call Saul."
Originally intended as a half-hour comedy, Better Call Saul will mainly be set pre-Breaking Bad in 2002 but jump across several decades.
This flexible timeline will "definitely" allow Breaking Bad characters to make reappearances, including Bryan Cranston as Walter White.
"Perhaps some of it takes place before Breaking Bad, during Breaking Bad and after Breaking Bad," Gould said earlier this year.
"That gives us the ability to bring back characters that were killed on Breaking Bad."
Netflix original series to watch in 2014
Netflix original series to watch in 2014
1/10 House of Cards
Back for Season 2. This run of the murky political thriller will see Kevin Spacey's wily congressman Frank Underwood finally get 'one heartbeat away from the presidency' but face attacks from all sides.
2/10 Better Call Saul
We're unlikely to see this Breaking Bad spin-off until 2015 but Walter White's crooked lawyer Saul Goodman will be back...
3/10 Orange Is The New Black
Back for Season 2. A dark comedy set in a tough women's prison that has transformed into a surprisingly macabre insight into how we selfishly cling to love in times of need, bolstered by some moving sub-plots.
4/10 Bojack Horseman
Speaking of Breaking Bad, how about a cartoon voiced by Aaron Paul aka Jesse Pinkman that follows a whiskey-drinking horse with a bad case of ennui? Thought so.
5/10 The Killing
Back for Season 4. The Killing refused to be killed last year, saved from the chop for a final season exclusive to Netflix to expedite the mopping up of plot lines.
6/10 Hemlock Grove
Back for Season 2. Fans of True Blood, The Walking Dead etc might find reason to return for this second batch of 'mild fornication, fellatio, heavy cocaine use, lesbian necrophilia and violent hemorrhaging'.
7/10 Sense 8
The always mind-bending output of Andy and Lana Wachowski (pictured) will be funnelled into the small screen for the first time with this sci-fi series, which, like the siblings' recent film Cloud Atlas, will focus on a series of seperate and yet interweaving stories.
8/10 Untitled - from the creators of Damages
The Damages creators left Netflix chiefs 'spellbound' when they pitched this as yet untitled 'suspenseful family drama'. It will centre on a family whose secrets and scars are revealed when their black sheep brother returns home, which all sounds a bit Brothers & Sisters, only this is Netflix so there will probably be some sex and fratricide in there somewhere.
9/10 Marco Polo
Fortunately for the easily bored modern viewer, this nine-chapter series will not focus on the famous explorer's influence on European cartography but his encounters with 'astonishing martial arts, sexual intrigue, political skullduggery and spectacular battles'. Hurray!
Notorious drug lord Pablo Escobar has seen several film biopics but comparatively few portrayals on television. This is set to change with Narcos, which will chronicle his life and death in a collaboration with Gaumont International Television.
Aaron Paul, who played Jesse Pinkman in Breaking Bad, also said he would be keen to return for Better Call Saul.
"I'd love to be a part of it," he told AMC in June. "I'm so jealous that everyone is back in Albuquerque, back in the same stages where we shot Breaking Bad."
Odenkirk revealed on Sunday that he has yet to watch himself in Better Call Saul, believing it is a "perfectly good way to approach acting to not know what the f*** is going on".
"I really don't want to know what's coming later and I don't look back at what came before," he said.
While filming season three of Breaking Bad, however, Cranston called Odenkirk out on his acting technique when he referred to a character whom Saul did not like in the wrong tone.
"That guy's not your friend, don't say it like that," Odenkirk remembers his co-star saying. "You don't watch the show, do you?"
Despite the first series not airing until February Better Call Saul has already been confirmed for a second run.Reuse content
