Since the film was released in 1997, the famous theme song immortalized by Celine Dion has been played at more than one wedding. It's no coincidence: Titanic is one of the most iconic romantic films in cinema history.

While this movie is full of memorable love scenes, the one that has remained in our hearts is that of Rose (Kate Winslet) and Jack (Leonardo DiCaprio) putting their class differences behind and kissing at sunset on the ship's bow. Have you ever exclaimed, "I'm flying" while embracing your beloved? We bet many of you have!

The basis of a successful romantic relationship is a beautiful friendship, and When Harry Met Sally is proof of that —even if it takes the main characters the whole film to figure it out!

Over the course of an hour and a half, spanning 12 years in the life of this couple, we see how they fall in love, even though they sometimes get on each other's nerves. In the end, during a New Year's Eve party, Harry (Billy Crystal) finally declares his love to Sally (Meg Ryan), who can't resist her friend's charm. Is When Harry Met Sally the ultimate rom-com of all time? Most definitely!

Have you ever heard the phrase, "If you love somebody, set them free"? That's what Rick (Humphrey Bogart) must have been thinking when, at the end of Casablanca, puts his life in danger to help Ilsa (Ingrid Bergman) flee to safety along with her husband.

Rick and Ilsa's relationship never materialized, but it has undoubtedly left us with one of the most iconic love stories the silver screen has ever produced. Yet, as a consolation, we'll always have Paris!

Undoubtedly, the chemistry between Ryan Gosling and Rachel McAdams has catapulted The Notebook to the podium of the most romantic movies ever. Twenty years after its release, it’s still one of the favorites among fans of the genre!

It’s very hard to choose just one romantic scene from this movie. All of it is an ode to love—and heartbreak. But perhaps the one that comes immediately to mind when we mention this film is the passionate kiss in the rain. Caught in a sudden storm, Allie finally confronts Noah for not writing to her for 7 years. Words certainly fall short of explaining the misunderstanding!

Not all love flicks have a happy ending, and that doesn't make them any less romantic. In The Bridges of Madison County, Francesca (Meryl Streep), a devoted housewife, meets Robert (Clint Eastwood), a free-spirited National Geographic photographer, while her family is away.

Francesca and Robert share a passionate week together but soon must return to reality. At the end of the film, Francesca faces two choices: be obedient and stay with her husband and children or give it all up for the love of her life. The scene in the truck, where she sees him standing in the rain and is about to leave everything for love, is so full of emotion that it is almost painful to watch.

Thanks to this film, pottery will be linked to romance forever. In one of the most iconic scenes in Ghost —and cinema in general— Molly (Demi Moore) can't sleep, so she decides to get to work. While modeling a vase to the rhythm of Unchained Melody she is joined by her steamy boyfriend Sam (Patrick Swayze).

With this scene, the film succeeds in capturing a moment of passion but also of emotional connection between two people. It is a scene of intimacy and sensuality rarely achieved so well on the big screen.

The relationship between Scarlett O'Hara (Vivien Leigh) and Rhett Butler (Clark Gable) is as complicated as it is passionate. During nearly four hours of film that covers more than 10 years in the life of this tumultuous couple, we see their comings and goings, tender moments, and fierce fights.

Perhaps the most memorable scene in this film is the first kiss under the bright orange sunset. This, along with other equally romantic scenes, has made Gone with the Wind one of the best romantic films in the history of cinema, despite being 85 years old.

​​Sleepless in Seattle is another rom-com that can't be missing from this list. In a nutshell, this is the story of a widower (Tom Hanks) looking for a new partner and mother for his son and a woman (Meg Ryan) who discovers that the love of her life might be on the other side of the country. Sounds like the formula for success, don't you think?

But did you know that the film's most memorable scene—the one in which Sam and Annie finally meet at the top of the Empire State Building—almost didn't happen? Rumor has it that the producers didn't have clearance from the building's owners. Luckily, director Nora Ephron had an ace up her sleeve and got permission to film for a mere six hours, which was enough to make this scene unforgettable.

Who said there can't be romance in an animated movie? Up is one of the favorite films among children and adults alike. In the very beginning, a montage shows us the love story of Carl and Ellie, from childhood to old age.

Throughout their life story, we witness beautiful moments such as their wedding, as well as heartbreaking events. These few scenes really have all the necessary condiments to make us laugh, love, and cry in just a few minutes.

Will artificial intelligence be the future of love? We don't know, although Her tries to explore what romantic relationships would be like in a hyper-connected tomorrow. Unable to get over a breakup, Theodore (Joaquin Phoenix) begins a romantic relationship with "Samantha," his computer's operating system.

In a heartbreaking scene, Samantha asks, "Are these feelings even real?" The love between them grows deeper each day, even though they cannot explain how it came about between a human being and a machine. Probably not your standard rom-com, but certainly a film that takes the subject of love to unexpected territories.

"Love means never having to say you're sorry," says Jenny (Ali MacGraw) to Oliver (Ryan O'Neal) in a film considered one of the most romantic by the American Film Institute.

Although it has a sad ending, Love Story succeeds in masterfully and eloquently portraying the story of two young college students who fall deeply in love despite their differences.

Is there such a thing as love at first sight? If you don't think so, then you should see Before Sunrise. In this endearing film, two strangers meet on a European train and end up roaming Vienna together all night.

In one memorable scene, Jesse (Ethan Hawke) and Céline (Julie Delpy) pretend to talk to their friends back home. When Jesse asks her what she likes about him, Céline replies, "I like to feel his eyes on me when I look away." Pretty romantic, don't you think?
