Leo Barraclough International Features Editor David Wnendt, the German director behind controversial coming-of-age movie “Wetlands,” Hitler satire “Look Who’s Back” and teen crime drama “Sun and Concrete,” is once again pushing boundaries with his next feature film project. Backed by distributor-producer Constantin Film and with Seven Elephants lead producing, Wnendt has embarked on the feature film adaptation of the award-winning novel “Athos 2643” by Nils Westerboer. Wnendt, who will both write the screenplay and direct the theatrical film, promises an “emotional and spectacular experience that will take the audience into the vastness of outer space,” according to a press statement.
