Cast of King Arthur

King Arthur is a 2004 historical adventure film directed by Antoine Fuqua, featuring an ensemble cast with Clive Owen as the title character, Ioan Gruffudd as Lancelot, and Keira Knightley as Guinevere. The film reinterprets Arthur as a Roman officer, departing from the typical medieval knight depiction. It explores the 'Sarmatian hypothesis,' connecting the legend to the Sarmatian heavy cavalry troops in Britain and proposing Lucius Artorius Castus as the historical figure behind the legend.
