I know I don't normally post on Sundays but, well... you can see why I am already. This website from the Netherlands here has put up their pre-sale page of the Call Me By Your Name blu-ray (which they have listed for the end of June!) and the page includes a couple of never-before-seen behind-the-scenes shots from the movie, including this quite spectacular one seen here.
This is not a scene in the movie but I'm guessing it's from one that got cut (as opposed to just a picture of the actors hanging out on set, that is) and I'm guessing I know when in the movie it would've taken place too since Elio's parents clothes are the same ones they're sunning in when they have the conversation (which is in the final film) about letting Elio go away with Oliver before Oliver leaves for good. I'm also guessing that this edited-out-scene then is the source of this shot...
