PSA: shedding a tear is scientifically proven to release oxytocin and endorphins, which is why you often feel better, or calmer, after a good cry. Which is surely as good a reason as any to pop on a film that could well make you weep? The thing is: the best sad movies are never just sad. To earn your emotional investment and bring you to the point where liquid actually leaks from your eyes, you have to fall in love with the characters and live their journey along with them. So, yes, you will cry a number of times, but you will also laugh, sweat, dance and have many epiphanies, to paraphrase Gwyneth Paltrow (who does not otherwise feature in this list). Below, Vogue lists 41 of the saddest movies of all time, all but guaranteed to induce a cathartic crying jag.
