The behind the scenes for breaking bad and better call Saul are fantastic, couldn't recommend them enough.

Best part of the breaking bad ones is what a shit Bryan Cranston is. Don't get me wrong, he's delightful, but he's constantly fucking with everyone and it's great.

One prank he would pull on Aaron Paul (Jessie) is pretending his character had been killed off. He'd go up to him, tell him how great it was working together on the show, and how he would do great things after leaving, only for Aaron to panic, rush to get the script, and find out he survives.
