The plans have been floating around since last winter, but now it’s official: The BBC and BBC America will co-produce a seven-part miniseries adaptation of Susanna Clarke’s best seller Jonathan Strange & Mr. Norrell, to air in 2014. For the uninitiated, Strange follows two magicians through early-1800s Britain, so if Dan Stevens has any sense left, he is currently begging his way into the project. Surely Downton fans could forgive a costume drama with magic.
