1. TNT, Showtime, FX and HBO all passed on the show.

2. The show was to take place in California - it was switched because New Mexico has better tax rebates.

3. John Cusack and Matthew Broderick turned down the role of Walter White. Bryan Cranston was hired after exec's were shown an episode of "The X-Files" he was on.

4. In the original script, Walter was to push Janes head back for her to choke, making him directly responsible. It was later changed to what we saw, him doing nothing as she accidentally chokes.

5. Jesse was supposed to die at the end of season 1, but after seeing Aaron Paul's performance, Vince Gilligan changed his mind.

6. Mike Ehrmantraust's role was also supposed to be smaller, he was only introduced because Bob Odenkirk (Saul Goodman) wasn't available to film and they created a throw away part. They liked him. His role got bigger.
