The veteran actor went on to add, “About half the crew I worked with on The Crown, which, until now, is the best television I’ve ever done. You put on that beard down to here, these long cloaks and the floppy hats; it’s magic!” He hailed the marvelous actors he was working with while also revealing that the previous Harry Potter, Daniel Radcliffe, came to see him perform in Giant on Broadway. Lithgow shared that Radcliffe was “wonderful.” Dominic McLaughlin takes over the role of young wizard Harry Potter on the HBO show. His best friends, Ron Weasley and Hermione Granger, are played by Alastair Stout and Arabella Stanton, respectively.
