After its London run, the production toured the UK and the United States, returned to the National Theatre in 1993 and was then presented in Athens and Israel in 1994. Hawthorne repeated the role in the 1994 film, earning a Best Actor nomination in the Academy Awards.
The play has been viewed as a character study for the actor who plays George III and most reviewers attribute its success to compelling performances from the two actors, Hawthorne and Haig, who played the king. Frank Rich of The New York Times singled out Nigel Hawthorne's performance in the US tour, calling it "astonishing" and "unforgettable", but he labelled the play itself as not "one of Bennett's major works" and as being more "marketable to Broadway and the colonies".[7] Writing about the 2012 revival, Lyn Gardner said that Luscombe's production reminds us that "Bennett is not writing a royal Downton Abbey, but a play exploring appearance and reality", and that the play brings out the fact that amidst all the royal pomp the king is merely a man like everybody else.[8] In The Telegraph, Charles Spencer praised Haig's performance, comparing it favorably to Hawthorne's performance twenty years earlier, saying "it seemed an impossible act to follow, but David Haig proves every inch Hawthorne’s equal in a performance of extraordinary emotion, tenderness and humour".[9]
Writing on the 2018 Nottingham Playhouse run, Kate Maltby, writing for The Guardian notes that "Scarborough and Gatiss are electric", praising Gillettfor her "endearing" portrayal of Queen Charlotte. She notes that "Gatiss delivers a tour de force" in this "viscerally repulsive depiction of the gap between public and private life." even despite his descent into a "slobbering wreck" as George III. Maltby notes overall that this production is a "technically excellent production of a modern classic." gaining it a 4 out of 5 rating.[10]
