This from Forbes.com:
"To compile our list we considered romantic parings that had appeared in at least two films together in the past 20 years. We ranked the pairs based on non-inflation adjusted worldwide box office grosses, as calculated by Box Office Mojo. Animated movies were not included."
Topping off the list with $2.9 billion in worldwide earnings is everyone's favorite sword-weilding "interracial" couple: Viggo Mortensen and Liv Tyler as Aragorn and Arwen in Peter Jackson's epic trilogy "The Lord of the Rings."
Falling just short of the pointy-ears-and-pointier-swords Middle-earth couple is our beloved "tiger," Spider-man, with his "Marvel"-ous redhead, Mary Jane. As if I needed to say this, they were played by Tobey Maguire and Kirsten Dunst for three consecutive web-headed movies.
Trailing behind at slot #3 are Leonardo DiCaprio and Kate Winslet, who shared two very different, yet both ill-fated, romances on the big screen, first in "Titanic" and then in "Revolutionary Road." The movies brought in $1.8 billion and $75 million, respectively, worldwide.
Slot #4 belongs to the two "Transformers" movies, which together raked in $1.5 billion worldwide. And no, it's not the touching love story between Sam and Bumblebee. Sadly, many moviegoers actually do find the chemistry between Shia LaBeouf and Megan Fox endearing.
Bringing up the list's tail is a couple that could very well overtake some of even (hope not) all of the other contenders. Why do I hope not? Well, this couple sucks...literally. The vampiric romance between Robert Pattinson's Edward Cullen and Kristen Stewart's Bella has sucked $1.1 billion out of the world's wallets so far with just two movies, and at least two more are on the way. After all, has a more romantic line than, "You're like my own personal brand of heroin," ever been uttered on camera before?
