Halloween Kills director David Gordon Green revealed one of the biggest challenges of filming the upcoming horror sequel had to do with Michael Myers' iconic mask.

During a recent Q&A at Beyond Fest (via ComicBook.com), Green opened up about some of the difficulties he faced while shooting the latest installment in his Halloween trilogy. "In terms of the challenges, I feel like I'm usually very prepared for either the technical or the performance. And there's always a curveball in one or the other of them, on every scene," he said.

One of those curveballs involved figuring out how to showcase Michael's creepy white mask. "The Michael Myers mask, it only works in certain angles and certain lighting environments. So sometimes you'll get so caught up in dialogue that you'll think, 'Oh wait. But then the mask is not getting the love it needs by the lighting department,'" Green shared. "And so it's just kind of juggling all of those technical... I mean, there's no scene in this movie that's just two people talking in a room. So it gets very challenging trying to figure out where to prioritize. Is it in the atmosphere, is it in the technical, is it in the emotional?"

Fun fact: Michael's signature pale mask was originally created by spray-painting a William Shatner mask and changing the hair. However, the mask has gone through multiple iterations over the decades. In Halloween Kills, Michael's mask is significantly burnt as a result of the fiery conclusion to 2018's Halloween, where Laurie Strode (Jamie Lee Curtis) set fire to her home with Michael trapped in the basement. The latest sequel, which picks up immediately after the events of the 2018 reboot, sees Michael escaping to carry out yet another killing spree in the town of Haddonfield.

It's worth noting that the final trailer for Halloween Kills teases Michael's potential unmasking. "I want to take his mask off and see the life leave his eyes," said Curtis' character prior to another clip of someone attempting to remove the killer's iconic visage.

Meanwhile, Blumhouse -- the studio behind the new Halloween trilogy -- has tapped Green to direct a sequel to The Exorcist once he finishes shooting next year's Halloween Ends, the third and final film in the rebooted franchise.

Halloween Kills will premiere in theaters and be available to stream on Peacock starting Oct. 15.
