Inanna Sarkis (Boo 2! A Madea Halloween), Gregg Sulkin (“Runaways”), Timothy Granaderos (“13 Reasons Why”), and Paris Berelc (Hubie Halloween) will star in Ascent for director Adam Green (Hatchet, Frozen), Deadline reports.

The survival thriller follows a group of friends attending a destination wedding in Europe who find themselves stranded on a hot air balloon 3,000 feet in the air.

A previous report suggests that shark-infested waters may be waiting below.

“I’m incredibly excited to be returning to the survival thriller genre,” said Green. “Ascent’s story about a recreational activity gone terribly wrong is going to play with people’s real life fears and be a total thrill ride for the audience.”

Production is set to begin shooting in Malta later this month under Simple House Films.

“The film is a high-intensity thriller, set entirely in real time,” said Simple House’s Volodymyr Artemenko. “The gripping and anxiety ridden experience will be captured for the screen by a talented and creative team.”

Simple House Films was launched last year by Artemenko, Addam Bramich, and Ryan Hamilton. Ascent is the first title to be sold under its new international sales unit, spearheaded by Anastazja Bankowska.

Green has been a staple in the horror community since his 2006 slasher throwback Hatchet. Ascent marks his first time back in the director’s chair since the franchise’s fourth installment, Victor Crowley, in 2017.
