EXCLUSIVE: History is teaming with Bonnie & Clyde executive producers Craig Zadan and Neil Meron on a new four-hour miniseries. The network has bought a script for the project, from Sony TV and Zadan and Meron’s Storyline Entertainment, which tracks the origins of the mystic medieval Christian order known as Knights Templar. Written by Keir Pearson, an Oscar nominee with Terry George for Hotel Rwanda, the mini tells the true story of three brothers, all knights, during the first Crusade, as they make the long journey through the Holy Lands to recapture Jerusalem, ultimately bringing rise to the Knights Templar. Zadan and Meron executive produce, with Pearson co-executive producing and Storyline VP Development Mark Nicholson, who brought in the project, serving as a producer. Like the Knights Templar mini, Zadan and Meron’s Bonnie & Clyde, also from Sony TV where Storyline has a longform deal, was originally set up at History before becoming a three-network event, airing simultaneously on History and A+E siblings Lifetime and A&E. Zadan and Meron recently signed on to return as Oscar producers for a third straight year. They also are working on NBC’s Peter Pan, the follow-up to the their hugely successful live staging of The Sound of Music last year. Pearson, repped by manager Adesuwa McCalla and attorney Nina Shaw, recently penned the Lionsgate feature Cesar Chavez.
