After the A Complete Unknown star's surprise SAG win, viral acceptance speech and attention-grabbing campaign, could he pip Adrien Brody to the post to win the coveted best actor prize?

He turned up to his premiere on an e-bike; crashed his own lookalikes contest; laughed at all the times he failed to win awards on Saturday Night Live; and on Valentine's Day he arrived in Berlin's sub-zero temperatures bare-shouldered, in a powder pink vest. Over the course of a few weeks and months, Academy Award nominee Timothée Chalamet has upended the idea of how awards honourees behave in order to secure votes. Could he still be rewarded with a best actor Oscar on 2 March?

It would be a major upset even for this extraordinary awards season if so, as the favourite for the prize, Adrien Brody, who plays a Holocaust survivor in Brady Corbet's The Brutalist, has won the Golden Globe, Bafta and Critics Choice Awards – all traditional harbingers of the Oscar. But then 29-year-old Chalamet took the SAG (Screen Actors Guild) prize for best actor on Sunday for his role playing a young Bob Dylan in James Mangold's biopic A Complete Unknown, accepting the award with an earnest speech that went viral.

Until that moment, he was at least winning the award for "one of the most gonzo best actor campaigns in Oscar history", as Variety describes it. Apart from the e-bike incident in London and poking fun at his "loser" awards face on Saturday Night Live, he chatted with Kendrick Lamar ahead of Lamar's performance at the Superbowl half-time show, and impressed on sports channel ESPN by making accurate college football predictions. (Some were moved to label him "Lisan al-Gaib" for this, in reference to the seer-like figure from Dune: Part Two, which along with A Complete Unknown, makes two best picture nominees in which Chalamet stars.)

"What I find most interesting is everyone's reaction to it," Variety's Chief Awards Editor, Clayton Davis, tells the BBC about Chalamet's campaign. "It varies from, 'Oh my god, the guy is an artist and he's our generation's James Dean, our Marlon Brando,' to older people........
