The adventure epic’s cast is led by Charlie Hunnam as King Arthur, Jude Law as Vortigern and Djimon Hounsou as Sir Bedivere. Astrid Berges-Frisbey, Aidan Gillen, Eric Bana and Mikael Persbrandt all appear too, while David Beckham has a small supporting role as a grumpy and apparently grotesque-looking knight.
