Breaking Bad is hailed as one of the greatest TV series of all time, thanks in part to its phenomenal cast of characters. However, a key character in AMC's crime series almost didn't make it, if not for the insistence of creator Vince Gilligan.

Saul made his debut in season two of the original program, before his back story was explored further in Better Call Saul. However, writer Peter Gould dropped a huge bombshell that executives didn’t love the character at first, and actually asked for another storyline to be used instead.

Since its debut, Better Call Saul has managed to establish itself as one of the best series of the last decade. This spin-off of Breaking Bad not only captured the essence of its predecessor but also carved its own path to success.
