It's well known that Cranston and Aaron Paul developed a strong friendship over the course of the show, but another person Cranston grew close to during the filming of the show was Anna Gunn, who played his wife Skyler. While they may have had an incredibly twisted, toxic relationship on the series, when the cameras stopped rolling the two were actually very good friends. There were even times when he found himself having to apologise to Gunn, because of things he said while in-character that ended up feeling a little too personal. As a result of this, and the growing bond between the pair, he would act as though he were genuinely protective and possessive of her on and off set. For example, when Chris Cousins - the man who played Ted Beneke - arrived on set, he'd be horrible to him, making remarks such as "Oh, boy - heres the asshole," because he had cultivated the feelings of jealously and resentment through building a close relationship with Gunn, something which transferred across to his performance.
