13 Steamiest Incestuous Relationships In Film By Roger Nackerman  [2 more lists]

You knew this was coming. The most famous case of incestuous relations in pop culture. Luke Skywalker was enamored with the idea of saving a beautiful princess and considered himself a rival of Han Solo's for Princess Leia's affections for most of the original Star Wars trilogy. (Check College Humor's edit to see just what Han was thinking.)

Long before it is revealed to them that they are in fact brother and sister, the most famous twins in a galaxy far far away lock lips in the scene to the left, complete with reaction shots.

If you think that's creepy, in 1978 there was a sequel novel to the original Star Wars (before the rest of the trilogy came out) called "Splinter of the Mind's Eye". In fine piece of somehow-published slash fiction, Luke and Leia are stranded on a swampy planet alone. The amount of sexual tension in the book is palpable and there is even a scene where they playfully wrestle in the mud and nearly kiss. The book was meant to be a low budget sequel in case the first film bombed. I think they should've filmed it anyway.

Back to the F*ture is one of the greatest science fiction films of all time, but it's all really a cover for making a movie about a mother having the wrong kind of feelings for her son.
Marty McFly inadvertently goes back to 1955 and prevents his parents from meeting, at which point his mother becomes infatuated with him. Not only does she come on to her son, but they even go ""parking"" during the ""Enchantment Under the Sea"" dance.
Oddly (and very creepily) a segment of the internet populace has made videos in support of the relationship. Weird.
Back to the F*ture trivia: When Robert Zemeckis was trying to sell the idea of this film, one of the companies he approached was Disney, who turned it down because they thought that the story of a mother falling in love with her son (albeit by a twist of time travel) was too risqué for a film under their banner. In fact, Disney was the only company to think the first was risqué. All other companies said that the film was not risqué enough, compared to other teen comedies at the time (e.g. Fast Times at Ridgemont High, Revenge of the Nerds, etc).
The video features a collection of the Marty and Lorraine scenes that ask, ""What would you do?""

The Lion King is the story of lion cub, Simba, who witnesses his father Mufasa's death and is guilted into exile by his evil uncle Scar. While in exile he is reunited with a cub from his pride named Nala. Nala and Simba fall in love and make with the love on their first date, because Nala was raised, literally, in the wild.

If you've ever watched Animal Planet or a documentary on Discovery about lion prides you know that a pride is made up of one male lion and a bunch of hungry, controlling, horny lionesses. The male is the only one who sleeps with these lionesses and is therefore the father of any cubs in the pride. Based on this knowledge of how the animal kingdom works we can assume Mufasa is the daddy of both Simba and Nala; making both of them half-siblings.

Thanks to Disney (and the story they originally stole the Lion King from), you can now never unlearn this.

To make matters worse, in the Lion King sequel the pair have had a cub of their own who falls in love with Scar's son. Remember, Scar is Simba's uncle, meaning even in the second generation the Lion King kept it in the family.

This comes to mind when taking all of this in and was intentionally excluded because c'mon, seriously.

Not really related, but you need to see this mash-up of The Lion King with the audio of Dark Knight Rises. Simply amazing.

Keanu Reeves plays hot shot lawyer Kevin Lomax, who Al Pacino has big plans for at his very high profile law firm in New York.

Thing is, Al Pacino is the Devil, and he's really trying to get Keanu to join the family business. Yup, Keanu is the son of the devil. Keanu is married to Charlize Theron in the film, but that won't do at all, because daddy has someone special in mind for our Mr. Reeves. Connie Nielsen plays Christabella, a temptress that has Kevin Lomax (Keanu) thinking, "Charliz-eh who?"

In the scene to the left, the final scene in the movie (spoiler alert for those who hate themselves enough to watch this and attribute absolutely no value to their time enough so that watching The Devil's Advocate seems like a good idea), Al Pacino plays match maker between his son Kevin Lomax and Christabella, his daughter.

And it's at this point Keanu and Connie get into some hot and heavy action as brother and sister, with Keanu even uttering the line, "I've wanted you since the day we met" which for MOST brother/sister couples is the moment the younger one was born.

Michelle Trachtenberg is insanely hot. After years and years mired in little sister and teen roles, she finally got to show off her sex appeal in Eurotrip as the also insanely hot character "Jenny".

As four friends made their way across Europe she and her brother had a number of misadventures, possibly the worst of them, though, is featured in the scene to the left where twins Jenny and Jamie end up getting so drunk on Absinthe they have no idea who they're making out with. T

he incestuous liaison happens at the 3:30 mark and is... uh... yeah...
