Irish actor Colin Farrell is in talks to portray mythological British knight Sir Lancelot in a fantasy film adaptation of the King Arthur legend.

Warner Bros movie executives initially scrapped plans for the Arthur & Lancelot project in January due to budget concerns, but they are now looking at reviving the film with the Phone Booth star as King Arthur's most trusted knight.

The Killing actor Joel Kinnaman had previously been cast in the role, opposite Kit Harrington.

David Dobkin had been due to direct that project and he is expected to remain in charge of the new film.

Arthur & Lancelot isn't the only Warner Bros movie focused on the King Arthur era - filmmakers Guy Ritchie and Bryan Singer are also working on their own adaptations.
