The cast of Stranger Things - including Millie Bobby Brown, Noah Schnapp, Sadie Sink, Finn Wolfhard, Eduardo Franco, Charlie Heaten, Gaten Matarazzo, Caleb McLaughlin and Priah Ferguson - talk to BBC Radio 1's film critic Ali Plumb over the magic of the internet as season 4 (part 1) finally arrives. The cast chat about "spoiler reaction faces", bloopers, dancing and fans being weirded out that - somehow! - they've all grown up over the past six years. Imagine that, eh?
