Daniel Fienberg sends this along: What better way to kick off this January’s Television Critics Association press tour than with Sir Ian McKellen discussing his upcoming Great Performances version of “King Lear,” which he acknowledges is generally a career-capping role for most Shakespearean actors. “If, like me, you’ve worked your way through Shakespeare as an actor, waiting up there is King Lear and beyond him a shadowy Prospero maybe or a Falstaff,” says McKellen, who admits to being terrified of Falstaff. McKellen adds, “It’s the challenge. It’s the expectation that it will complete your journey through Shakespeare.” Of course, no matter how much acclaim McKellen gets for his stage work, he knows that he’ll always be recognized in the street for something different.
