Zac Efron and Seth Rogen are working on “Neighbors 3: Zombies Rising.” The movie promo shows the pair fighting off a zombie.

“Neighbors 3: Zombies Rising” sees the Efron-Rogen team trying to kill a zombie. It turns out that the thing in question is wearing a sorority tee and has the couple arguing about whether or not to kill it. But wait! It is not the third part of the series. It is just a promo featuring what the two actors made to promote their current movie “Neighbors 2: Sorority Rising.”

“Neighbors 2: Sorority Rising” has been received well by the audiences so far. It was expected to make around AU$34.6 million (US$25 million) over this weekend. However, Universal pictures released this zombie-based promo in an effort to further promote their movie “Neighbors: 2 Sorority Rising.”

Slash Film explains that the promo was aired during an episode of “Fear The Walking Dead” last weekend and according to MovieWeb, it will air during the “Preacher” premiere on AMC.

According to Uproxx, the one and a half minute clip shows Efron and Rogen trapped in a basement with a tied-up zombie. Rogen suddenly pulls out a sword to chop off its brains. However, Efron notices that it is wearing a Delta Psi T-shirt.

Efron doesn’t want to kill his “brother.” “I know you can’t see it, but underneath that messed up face, there’s a cool brother,” pleads Efron. “When you’re brothers, it’s forever — for life and beyond, okay?” he adds. Efron and Rogen fight over it and the problem gets solved.

After watching the promo, many felt that a “Neighbors 3” won’t be a bad idea at all. “Men in Black” and “21 Jump Street” are having a crossover already. It is titled “MIB23” and is being helmed by James Bobin. Bobin has also directed the “Alice” sequel titled “Alice Through the Looking Glass.”
