The Looper helmer has directed two episodes of the AMC drama to date – season three's 'Fly' and season five's 'Fifty-One' – and will return to direct the sixth episode of the show's final eight-episode run, which began filming last month.
"I'm so excited," Johnson told Digital Spy about his return. "And it was a last-minute thing, where the schedules shifted around.
"They had told me 'no, we're totally full up on the last season', and I told myself 'OK, that's great, that means I'll get to just watch it as a fan'. But then Melissa, one of the producers, emailed me and I was like 'Yes, please!'"
Johnson went on to discuss the differences between his prior two episodes, describing the bottle episode 'Fly' – which is largely a two-hander between co-stars Bryan Cranston and Aaron Paul – as "a very unique challenge".
"[The two episodes] were night and day. I guess it's pretty obvious why 'Fly' was a unique experience, it was more like doing a play than anything else.
"It was just these two guys, mainly on one stage, and directing was largely just figuring out how best to showcase their performances, and keep it visually interesting. Keeping that space from feeling like you were trapped in it, or actually making you feel like you were trapped in it, at times.
"It tends to go either way with fans of the show, which I completely understand, it's pretty polarising, which I think Vince [Gilligan] knew when he gave me the script. He was like 'this is something that some people are going to see as filler, and some people are really going to dig into'."
The final eight episodes of Breaking Bad will air on AMC this summer.
