Arrow Films in the UK are going to release The 'Burbs on Blu-ray in the UK. It's unknown at this time however when the Blu-ray will be released. The release was confirmed in a recent pretentation reel which includes releases from the past, present and the future. You can watch the presentation reel here:
If only, but it doesn't look like it's happening any time soon.
I fully suspect, what with their influx of Universal licences, that Shout Factory will get to THE 'BURBS at some point. Hopefully MATINEE too. But anyone who really cares about films should have a multi-region player anyway. It opens a whole world of possibilities to you.
French label Carlotta Films has revealed that it plans to add a number of titles to its Blu-ray catalog in 2014. Amongst them are Joe Dante's The 'Burbs (1989), Todd Haynes' Velvet Goldmine (1998), Max Ophüls' Letter From an Unknown Woman (1948), Alejandro Amenábar's Tesis (1996), and Fritz Lang's Secret Beyond the Door (1947).
