Has there ever been a romance film more iconic than Love Affair? Modern moviegoers might find the plot a tad simple, the scenes too reliant on dialogue, and the pace a bit slow, but this film is a classic for a reason. Love Affair works through good ol’ fashioned chemistry. It’s easy to credit this dynamic through the performances, which, yes, Irene Dunne and Charles Boyer deliver. But this dynamic was helped by the writing, with its natural slow build, great structure, and a relaxed demeanor that could only come about on vacation. It’s what makes the initial spark believable, and it’s so satisfying to prove that spark to be worth it when they continue to think the best of each other even when they have reason to believe otherwise. While its remake An Affair to Remember surpassed it in popularity, Love Affair still stands the test of time, setting the standard for all romance films to follow.

Major spoilers: Because of censorship, Terry gets the accident to give her an equal punishment for adultery, but this accident actually strengthened their reunion, giving a reason strong enough to delay gratification for a more romantic finale.
