David Heyman’s Heyday Films, the company behind this year’s hot Oscar contenders “Once Upon a Time in Hollywood” and “Marriage Story,” is set to produce “Shackleton,” the long-gestating biopic of legendary polar explorer Sir Ernest Shackleton, with Tom Hardy on board to play the title role. Hardy will also produce the pic alongside Dean Baker through their banner Hardy Son & Baker (“Taboo & Christmas Carol”) which originated the project.
