Colin Farrell is in talks to star in Warner Bros.’ “Arthur and Lancelot.”

David Dobkin is writing and directing the pic, which was expected to go into production in January but wound up postponed due to budget and other concerns. Charles Roven will produce.

At the time Kit Harington was set to play King Arthur and Joel Kinniman was on board to play Lancelot, but when Warners pulled the plug both actors fell out due to scheduling conflicts.

With Farrell the film not only looks to be up and running, but the studio now has a more recognizable star in place. Some sources said the lack of that star was part of the reason Warners was wary about moving forward in January.

Plot details are vague. Though Dobkin is known more for his comedies like “The Wedding Crashers” and “The Change-Up,” insiders said this pic will be more of an action pic in in the vein of “Braveheart.”

Dobkin will also produce with Roven, Richard Suckle and Lionel Wigram.

CAA-repped Farrell will be seen next in Sony’s reboot of “Total Recall.”
