American actor John Lithgow won the Best Actor trophy at the London stage Olivier Awards on Sunday for exploring the dark side of children's writer Roald Dahl in “Giant.”
The star of Conclave and the future Professor Dumbledore in the new HBO Harry Potter remake added the Olivier to an awards shelf that already includes multiple Tony, Emmy and Golden Globe trophies.

In Mark Rosenblatt’s play, he depicts the author of “Charlie and the Chocolate Factory", which confronts Dahl’s antisemitic views.
“I think I'm going to faint,” said an emotional Lithgow, 79.
While accepting his award, he appeared to reference the current controversy over Donald Trump's second term as US president, assuring Britons that the transatlantic "special relationship is still firmly intact.”
“It’s not always easy to welcome an American into your midst, and at this particular moment, it’s probably a little more complicated than usual,” he told the audience at the Royal Albert Hall.
Giant was also named Best New Play, and Lithgow’s co-star, English actor Elliot Levey, took Best Actor in a Supporting Role.

Elsewhere, the backwards-biographical story “The Curious Case of Benjamin Button” - the musical based on a story by F. Scott Fitzgerald that also inspired David Fincher’s 2008 movie starring Brad Pitt - was named Best New Musical at the awards, while acting legend Lesley Manville took the Best Actress prize for her performance as shocked royal spouse Jocasta in “Oedipus.”
Director Robert Icke’s modern-day reimagining of the ancient Greek tragedy was named Best Revival of a play.

Imelda Staunton won the fifth Olivier of her career, Best Actress in a Musical, for “Hello, Dolly!”, while Best Actor in a Musical went to John Dagleish as the titular man who ages in reverse in “Benjamin Button.”
