Fäh’s latest work is the upcoming survival thriller No Way Up for Altitude Film Entertainment and Ingenious Media, starring Colm Meaney (Hell on Wheels, Star Trek) alongside BAFTA Award winner Phyllis Logan (Downton Abbey), Sophie McIntosh (Brave New World) and Will Attenborough (Dunkirk). No Way Up is scheduled for a 2024 release in theaters and online worldwide.

In 2021, Fäh directed the fourth season of Switzerland's critically acclaimed Nordic noir sensation, Wilder. Produced by C-Films and SRF, this series achieved record-breaking ratings in 2022 and garnered praise from both viewers and critics. The show featured a talented ensemble cast, including Sarah Spale, Marcus Signer, Andreas Matti, László Kish, Jonathan Loosli, Annina Euling, Sabine Timoteo, Dimitri Stapfer, Nicolas Rosat, and Sebastian Rudolph.

Before writing, producing, and directing the award-winning short documentary Child of the Earth, which was selected at several international film festivals, Claudio Fäh directed the seventh installment of the Sniper franchise for Sony's Stage 6 Films and Mandalay Pictures: Sniper: Ultimate Kill. The movie achieved remarkable success on Netflix, reaching the top ten charts worldwide, clinching the #3 spot in the US. Fäh's return to the series after his well-received revival of the franchise with Sniper: Reloaded in 2011 was celebrated by fans and critics alike, with critics hailing it as the “best Sniper film since the first, nearly 25 years ago.” Ultimate Kill was shot in Bogota, Colombia, starring Chad Michael Collins, Danay Garcia, and reuniting the cast of the original movie: Tom Berenger and Billy Zane.

Fäh's World War II thriller, Beyond Valkyrie – Dawn of the Fourth Reich, also produced by Sony's Stage 6 Films, premiered in US theaters in July 2016, followed by a global release through Sony and Starz. This film starred Sean Patrick Flanery, Stephen Lang, Tom Sizemore, and Rutger Hauer.

In 2015, Fäh's epic adventure, Northmen – A Viking Saga, produced by Elite Filmproduktion and featuring a stellar cast including Tom Hopper, Ryan Kwanten, Ed Skrein, and James Norton, enjoyed a wide theatrical release across Europe and made its US theatrical debut through Anchor Bay/Starz. The film subsequently earned a place among the top ten best sellers in the home market. 

Before Northmen, Fäh directed several films for Sony's Stage 6 Films, including Hollow Man 2 and Sniper: Reloaded, and produced Starship Troopers: Marauder, which earned him two Saturn Award nominations. Additionally, Fäh produced Joe Dante's film The Hole, starring Haley Bennett, Teri Polo, and Bruce Dern. This movie earned recognition as the “Best 3D Movie” at the Venice International Film Festival and played at Midnight Madness at the Toronto International Film Festival.

For Sander/Moses Productions, Fäh directed the award-winning original web series Ghost Whisperer: The Other Side. This scripted online companion series to CBS's Ghost Whisperer clinched the TV Guide Online Award for “Best Online TV Drama.” CBS quickly greenlit a second season, also helmed by Fäh.

Prior to his feature film career, Fäh directed several short films, earning numerous international awards. In the commercial industry, he achieved recognition, including the EDI award for “Best Commercial Director” in his native Switzerland.
