Mr. Hiddleston has perhaps the most conspicuous royal shoes to fill, thanks to the memorable film performances of Henry V by Laurence Olivier (in 1944) and Kenneth Branagh (in 1989). "I knew that people would make comparisons," he said. "But I knew, somehow, that I'd find my own way."
Tom Hiddleston is not in the first "episode" (it is odd to think of Richard II as a TV episode!), but will be in the rest of the series (i.e., Henry IV, Part One and Part Two, and Henry V).
