New York – November 01, 2026 -- TESSAN has premiered Jump Into The Unknown, a documentary that follows adventure athlete and filmmaker Jamie Leibert and his wife, Sandra Zinovyev, on a 30-day expedition through the Swiss Alps.
Leibert, known as Captain Manicorn, is behind the "climb and fly" discipline, which combines big-wall climbing with wingsuit and mini-wing flights. His expeditions have taken him to more than 80 countries. Zinovyev is the film's director of photography and editor. Their three-legged rescue dog, Journey, joined them in the mountains.
