Just a year ago, a movie like Host was barely imaginable; now it seems almost inevitable. Director Rob Savage’s thriller — about a group of teens marooned at home during lockdown, who decide, just for kicks, to gather on Zoom and conduct a séance — inventively plays on our new anxieties, using face filters, software glitches and connection problems as plot devices. Host drew hundreds of thousands of new subscribers to the streaming platform that commissioned it, got Savage three new directing gigs, and is even about to get a theatrical run. – BBC
