An offbeat political thriller, a vampire horror film and a period drama about Shakespeare will go head-to-head Sunday at the BAFTAs, Britain’s biggest film awards, setting the stage for the Oscars. It was followed by 13 nominations for the vampire period horror film “Sinners” — which smashed the all-time Oscars nominations record with 16 selections — and Timothee Chalamet’s ping-pong drama “Marty Supreme” with 11 nods.
