US actor Michael B Jordan has scored a surprise win at the Actor Awards, formerly known as the SAG Awards, giving him a surge of momentum in the final weeks before the Oscars.

He was named best actor for his role in vampire horror Sinners, which also scored the top prize of the night - best ensemble cast.

"I don't even know where to begin, I wasn't expecting this at all," Jordan said in his speech, adding that he felt "so honoured and privileged" to have been nominated.

Accepting the best ensemble prize, his co-star Delroy Lindo said making Sinners had been an "incredible journey", adding: "Every single day we brought ourselves, our hearts, our souls, to this endeavour."

"To be recognised by you all, 'thank you' does not come anywhere near to encompassing what we feel, the gratitude," Lindo said.
