David Twohy has set up a trio of writing assignments, one of which will turn his original heist movie premise into “The Brazilian Job,” the sequel to the Paramount hit remake “The Italian Job.” Twohy, who has also been tapped by Paramount to direct his script “The Would-Be Warrior” for Nickelodeon Films and to write the sci-fi action film “The Break” for Columbia Pictures, found his way into the “Job” sequel by accident. “I came in to pitch my own heist picture called ‘The Wrecking Crew,’ something I planned to direct myself,’ ” said Twohy, who has directed “Pitch Black” and “The Chronicles of Riddick” and whose script credits include “The Fugitive” and “G.I. Jane.” Twohy said Donald De Line and John Goldwyn, who took the meeting, liked his idea, but suggested it would be best suited for the sequel. Twohy said yes, even though he was fully aware he would be waxed from “The Brazilian Job” directing assignment by returning director F. Gary Gray. Paramount made Twohy’s sacrifice more palatable by making sure he had another movie to direct. The studio and Nick’s Julia Pistor sparked to his script, “The Would-Be Warrior,” and set him as its director. “It’s a fantasy adventure in the ‘Jumanji’ vein, involving a modern 15-year-old boy who gets caught in a centuries-old feud between Norse gods,” Twohy said. “It’s good, crazy fun and after doing something as sober as ‘Riddick,’ it will be nice to follow with a picture that doesn’t take itself too seriously. It has visual effects and lots of action, but it pokes fun at other grandiose sword and sorcery epics.” Twohy will return to his sci-fi roots with “The Break,” a new version of the long-in-development movie “Alien Prison.” That film, which Wick has developed for years with a number of writers and such filmmakers as Roland Emmerich, had revolved around the escape attempt by a number of earthlings snatched by aliens for experimental purposes. In the version Twohy has hashed out with Wick and Fisher, “The Break” will have a more traditional jailbreak tone.
