This film is the most surreal on our list yet. If you know that some unexpected scenes can distract you from learning English while watching this drama, try to pick a different one. As the main hero bonds with the OS, you may uncover another level of how humans might be co-existing with technology and especially with AI.
As one of the main characters is only a voice, you can practise your listening skills without relying on visual clues. In terms of vocabulary, there are plenty of informal and slang expressions, but not only, e.g.: be nosy, feel mopey, marvel at things, be upfront with somebody, and put it all on somebody.
