The Eagle is a 2011 epic historical drama film set in Roman Britain directed by Kevin Macdonald, and starring Channing Tatum, Jamie Bell and Donald Sutherland. Adapted by Jeremy Brock from Rosemary Sutcliff's historical adventure novel The Eagle of the Ninth (1954), the film tells the story of a young Roman officer attempting to recover the lost Roman eagle standard of his father's legion in Caledonia. The story is based on the Ninth Spanish Legion's supposed disappearance in Britain. Historically, the purported disappearance of the Ninth Legion in Northern Britain is a subject of debate.
In the year 149 AD, twenty years after the Ninth Legion disappeared in the north of Britain, Marcus Flavius Aquila, a young Roman centurion, arrives in Roman Britain to serve at his first post as a garrison commander. Marcus's father, who was the Senior Centurion of the ninth, disappeared with the eagle standard of the ill-fated legion, and Marcus hopes to redeem his family's honour by bravely serving in Britain. Shortly afterwards, only Marcus's alertness and decisiveness save the garrison from being overrun by Celtic tribesmen in a local insurrection. He is decorated for his bravery but honourably discharged due to a severe leg injury.
