Breaking Bad

Sony and AMC were initially reluctant to cast Bryan Cranston because of his previous comedic roles. They approached John Cusack and Matthew Broderick for the role of Walter White. When they both declined, Vince Gilligan was able to cast Cranston.

The nature of Gus and Max's relationship is never explicitly stated. Giancarlo Esposito stated in an interview that it was a "possibly lover relationship". Vince Gilligan stated in an interview that they "probably were lovers".

Walter was originally written to be 40 years old. AMC felt that 40 was too young for Walter to have a mid-life crisis and requested his age change to 50.
