We haven't heard anything about the sequel Hansel & Gretel: Witch Hunters 2 since June 2013, when executive producer Adam McKay teased that the follow-up will be "insane." Over the weekend, Shock Till You Drop spoke with writer-director Tommy Wirkola, who revealed that the script is finished, but he's unsure if Jeremy Renner will be able to return, due to his increasingly busy schedule.

"I've written the script for it. I've given it to Paramount and it's up to them now. But I don't know what's going to happen. Jeremy [Renner] is so busy these days, I don't know how they're going to juggle all of that, but it's up to [Paramount]. We'll see. Hopefully, I'll get to do another film first. They really liked the script I gave them. The first film was a learning curve for me working in the studio system and the script I wrote for the original was so different. We ended up taking a lot out and altering stuff that first time. I'm smarter now. I tried taking what I learned and still delivered a sequel script that's an R-rated action film."

Jeremy Renner and Gemma Arterton starred in 2013's Hansel & Gretel: Witch Hunters, which took place 15 years after the fairy tale characters' incident at the gingerbread house. The siblings now make a living hunting down witches and other creatures. The original took in $226 million worldwide from a $50 million production budget during its theatrical run last year.

Jeremy Renner is currently shooting Mission: Impossible 5, and it was believed that he would start shooting his follow-up to The Bourne Legacy shortly thereafter. However, we reported last week that Universal is planning on bringing back Matt Damon and Paul Greengrass for a new Jason Bourne adventure, which will move forward before The Bourne Legacy sequel. It's possible that this move will free up some time in Jeremy Renner's schedule to make Hansel & Gretel: Witch Hunters 2, but that has not been confirmed.

We'll have to wait and see if Paramount gives the green light for this follow-up to start production, and if Jeremy Renner will return alongside his on-screen sister Gemma Arterton.
