Leonardo DiCaprio may have the backing of his Titanic co-star Kate Winslet in his bid for Oscar glory but he lost out to British veteran Tom Courtenay for an award chosen by the UK's leading film critics.
Winslet, 40, said she would be "surprised" if The Revenant star did not win the Best Actor Academy Award at next month's Hollywood ceremony.
But it was 78-year-old Courtenay who was named actor of the year for his role in British drama 45 Years at the London Critics' Circle Film Awards.
Speaking on the red carpet of the awards at London's May Fair hotel, Winslet said she believed it was "probably going to be Leo's year" at the Oscars after missing out with his previous five nominations.
"I think you can sort of feel it and I think everyone wants it for him," she said.
"It would be amazing. It's also quite difficult for me too because Michael Fassbender is also nominated and I was his right hand woman for three months making Steve Jobs. I saw how hard he worked and I thought his performance was extraordinary.
"But I think you can feel the temperature and it's probably going to be Leo's year."
Winslet was named supporting actress of the year at the Critics' Circle awards after playing Joanna Hoffman in the biopic Steve Jobs, a role which could also earn her second Oscar.
"I really can't believe it because it has been a very strong year," she said about her Academy Award nomination.
"No one has been a shoo-in. People have been flitting in and out of this best supporting actress category for quite some time.
"They were like the golden tickets this year. They were really very coveted spots, particularly in this category, so I'm absolutely thrilled. I loved the experience of making it so it's ultimate cherry on the cake to be nominated."
