National Geographic Channel has set three separate projects with Ron Howard and Brian Grazer, Alex Gibney and Tom Fontana, the network announced today during its panel at the Television Critics Association summer tour.

TCA-Logo-800x500Red Planet (wt), an event series which tells the epic story of the quest to colonize Mars, is executive produced by Imagine Entertainment’s Ron Howard and Brian Grazer and Justin Wilkes and Dave O’Connor of RadicalMedia. A hybrid of scripted and unscripted elements, Red Planet is set in 2032 and the present day, and includes interviews from present-day scientists and innovators who are preparing the way for the first manned mission to Mars in 2032. It’s slated to premiere on the National Geographic Channel in 171 countries and 44 languages in 2016.

Nat Geo also greenlighted Parched from Oscar-winning filmmaker Alex Gibney and his Jigsaw Productions, which looks at the global water crisis. Gibney will serve as executive producer of Parched, which will be created as a TV miniseries and as a feature documentary with a limited theatrical release. Both will air globally on the National Geographic Channels in 171 countries and 44 languages.

Nat Geo also ordered a pilot script from Tom Fontana and Barry Levinson (The Levinson/Fontana Co) for a potential limited series, Last Men Out. Based on Bob Drury and Tom Clavin’s book of the same name, Last Men Out dramatizes the heroic actions of a small band of Marines in the final days of the Vietnam War. Fontana will write and executive produce the series pilot through The Levinson/Fontana Co— the production company he co-founded with Levinson.
