What if The Walking Dead and Breaking Bad took place in the same universe?

What if Breaking Bad is actually a prequel to The Walking Dead, and it was Walter White who caused the zombie apocalypse?

We know, it's not a new fan theory. But for the benefit of those who are just hearing about it for the first time, Netflix has had a crack at trying to make you believe it.

The video points to four reasons that support the theory.

1. Merle's hidden stash of drugs in The Walking Dead episode 2 includes blue-sky meth – seemingly the same type which Walter White was making.

2. The red sports car that Walter bought for his son looks like the same one Glenn drove to lure the walkers away in The Walking Dead episode 2.

3. Daryl says, "I'm going to kill you, bitch". Sounds a little like something Jesse Pinkman would say.

4. Gus Fring was the first ever zombie. Remember his death?

Okay, so it's all a bit of a stretch. But it's fun to briefly entertain the idea that both shows are connected other than the fact that they're both on AMC.

The Walking Dead is still going strong in its seventh season – with Rick's gang facing a new threat in the form of Jeffrey Dean Morgan's Negan.

He killed Glenn and Abraham in the season premiere, but actress Lauren Cohan says Maggie will want vengeance.

"What Negan's actions do to Maggie is light this crazy fuse," she recently said. "And we'll see that burn pretty strong."

The Walking Dead airs on Sundays at 9/8c on AMC in the US, and UK viewers can watch every Monday at 9pm on FOX.
