Shooting begins today at Swiss locations on Markus Welter’s 3D horror slasher film One Way Trip.

The co-production between Zurich-based HesseGreutert Film and Vienna’s Superfilm is the first 3D feature film to go into production from Switzerland and Austria and is described by the producers as “an intelligent slasher film with gothic elements and an unexpected ending.”

Austrian writing duo Matthias Bauer und Bastian Zach’s screenplay focuses on a group of young people falling into the murderous clutches of a madman as they search for hallucogenic mushrooms in Switzerland’s Jura Mountains.

The cast is headlined by Sabrina Reiter, Melanie Winiger, Herbert Leiser, and Martin Loos.

The Euros 1.8m production has been supported by Switzerland’s Federal Office for Culture (BAK), Swiss Television SF, the Zurich Film Foundation, the Austrian Film Institute (ÖFI) and the Vienna Film Fund.

One Way Trip will be released theatrically in Switzerland next year by Ascot Elite Entertainment and in Austria by Thimfilm.

HesseGreutert Film had previously worked with Welter on his feature debut the thriller Night Rush (Im Sog Der Nacht) in 2008.
