Colin Firth and Sir Ben Kingsley will star in “The Last Legion” for Dino De Laurentiis Co., Quinta Communications and Zephyr Films.

Action-adventure pic is set during the fall of the Roman Empire when its last emperor, 12-year-old Romulus Augustus, ruled for one day before being imprisoned on the island of Capri. With the help of teacher Abrosinus (Firth) and legionnaire Aurelius (Kingsley), Augustus escapes to make a last stand for Rome.

Doug Lefler will make his feature-helming bow with the pic. His credits include Universal Home Entertainment’s “Dragonheart 2: A New Beginning,” which was produced by Raffaella De Laurentiis, and directing second unit on “Spider-Man” and “A Simple Plan.”

Producing are Dino, Martha and Raffaella De Laurentiis with Quinta’s Tarak Ben Ammar and Zephyr’s Chris Curling and Phil Robertson.

Producer’s consultant Pamela Pickering handles international sales for “The Last Legion.” A veteran of the international sales industry, Pickering has maintained a low profile since exiting her post as president of sales and distribution at Graham King’s Initial Entertainment Group two years ago.

Firth stars in Atom Egoyan’s “Where the Truth Lies.” That pic will bow in competition.

Kingsley stars in the TriStar Pictures release “Oliver Twist” and in Paul McGuigan’s “Lucky Number Slevin.”
