All3Media has struck a partnership with veteran non-fiction producers Jen Casey and Nick Gilhool for their new Los Angeles-based production venture, One Traveler.

Under the partnership, One Traveler will create and produce multi-genre documentaries and unscripted series across broadcast, cable, streaming and digital.

Recent outings for Casey and Gilhool include launching filmmakers Joe and Anthony Russo’s nonfiction label Wonderburst, where they produced “Captive Audience” for Hulu, “Larry Charles’ Dangerous World of Comedy” for Netflix, “Back from the Brink: Saved from Extinction”, a global IMAX film release narrated by Claire Danes, and docuseries “Slugfest: DC vs. Marvel” for Roku.

Last summer, Casey, Gilhool and Miziker Content partnered with bestselling crime novelist Michael Connelly to produce “The Wonderland Murders & The Secret History of Hollywood” for Audible where the series was #1 podcast worldwide. MGM+ announced the documentary series adaptation last week as part of their rebrand slate.

Jane Turton, All3Media CEO, said: “We are delighted to be partnering with Jen and Nick as they launch their new company and we look forward to working with them as they develop and produce great, new unscripted content.”

“We are excited to join All3Media and its worldwide family of creative producers. What a great group of people,” said Jen Casey and Nick Gilhool. “One Traveler is hitting the ground running with a multi-genre development slate, and we look forward to bringing compelling documentaries and unscripted shows to different platforms as we grow our new venture.”

Jen Casey’s previous credits as a creator and producer include NatGeoWILD’s popular docuseries “The Adventures of Dr. Buckeye Bottoms”, National Geographic film “Extreme Weather” and IMAX film “Tornado Alley 3D”, one of the giant screen’s highest-grossing documentaries, as well as projects for National Geographic, Discovery Channel, BBC Worldwide, Food Network and more.

Nick Gilhool has served as senior production and creative executive on some of TV’s highest- rated series across broadcast, cable, and streaming. These include NBC’s “Making It”, “Project Runway” and “Fashion Star”, Bravo’s “Top Chef” and “Work of Art”, TNT’s “Cold Justice”, and more. He has also previously headed up development and series casting for Discovery, and served as a longtime exec at Magical Elves, where his credits included award-winning Showtime series “Time of Death” and “The Real L Word”.
