It appears that Sex Education<\/a> has begun production on its upcoming fourth season \u2013 at least going by a post shared by star Asa Butterfield on Twitter.<\/p>\n The actor \u2013 who plays lead character Otis Milburn on the series \u2013 shared a snap of himself sipping from a mug outside a trailer, with the caption \u201cGuess who\u2019s back\u201d.<\/p>\n While that isn\u2019t exactly overt proof that filming has begun, it certainly points to that direction, especially when we consider that production was always expected to start this summer.<\/p>\n Guess who\u2019s back pic.twitter.com\/IBQBPCOs11<\/a><\/p>\u2014 Asa (@asabfb) August 5, 2022<\/a><\/blockquote>
