The Showtime-owned Smithsonian Channel and U.S. pubcaster PBS are partnering on a new nature doc about evolutionary biology.
When Whales Walked: Journeys in Deep Time (pictured) seeks to unlock the evolutionary secrets of crocodiles, birds, whales and elephants.
The two-hour film uses 3D graphics and CGI to offer explanations for how these species came to look and behave the way they do today, with actor Lee Pace (Halt and Catch Fire, The Hobbit, Guardians of the Galaxy) narrating.
When Whales Walked is produced by Twin Cities PBS and Shining Red Productions for PBS and Smithsonian Channel. Michael Rosenfeld serves as executive producer for Twin Cities PBS. Bill Gardner is executive in charge for PBS. Executive producers for Smithsonian Channel are Charles Poe and David Royle.
The film premieres June 19 at 9 p.m. ET/PT on the Smithsonian Channel and PBS.
