One of John Travolta’s only good movies of the last decade or so, and a darn good movie in its own right, “Face/Off”, has made writers Mike Werb and Michael Colleary in-demand little pups. The duo have been snapped up to pen a big-budget tentpole flick called “Alien Prison” for Columbia Pictures. The film is about a gang that plots an escape from their alien captors. The prisoners then hope to prevent a full-scale invasion of Earth. The duo also scripted the upcoming transcontinental railroad epic “Men of Iron” for Face/Off helmer John Woo, says Variety.
