Actresses Dame Judi Dench and Emma Watson were among the stars honoured at the Britannia Awards, hosted by Bafta in Los Angeles.
Skyfall star Dame Judi said she was “overwhelmed” and “very proud” to be awarded the worldwide contribution award, named in honour of James Bond producer Albert “Cubby” Broccoli.
Former Harry Potter star Watson was named British artist of the year.
Robert Downey Jr was handed the Stanley Kubrick Award for excellence in film.
Other winners included director Mike Leigh, who won the directing award, and Veep actress Julia Louis-Dreyfus, who was honoured for her excellence in comedy.
The 79-year-old actress has starred in a string of box office hits in recent years, including Philomena and The Best Exotic Marigold Hotel, which has a sequel due in February.
“People like to say, ‘When are you retiring?’ Or ‘When are you going to slow down?'” she revealed on the red carpet.
“That’s all very rude in my family. We don’t say any of that. I think if I stop, it’ll be like a car – I shall run out of petrol and fall over. So, I plan not to do that, if possible.”
Watson, who was presented with her award by British actor Ben Barnes, paid tribute to Dame Judi.
“She’s just all soul and all grace and strength and beauty, and for me, she’s an iconic British actor. She’s what you aspire to be,” Watson said.
