WATCH: Exclusive trailer for US national parks documentary

Brought to you by MacGillivray Freeman, a new film is coming to the big screen called National Parks Adventure.
The U.S. National Park Service turns 100-years-old in 2016, which has prompted a new documentary to be released playing tribute to the wondrous national parks that are present in America.
The movie will be narrated by Robert Redford, and will feature the famous climber Conrad Anker, adventure photographer Max Lowe, and artist Rachel Pohl. The three will hike through America's most beautiful and well-preserved parks to commemorate and celebrate the mesmerizing wildlife that exists today.
The film will be released in both regular and IMAX theatres in February, and will additionally be sponsored by Expedia, Subaru and VisitTheUSA.com.
