This couple fell in love shooting Dream House and were married less than six months later.
Daniel Craig may work with some of the world's most beautiful women in the James Bond franchise but the British action star only has eyes for his wife Rachel Weisz.
The couple had been friends for years before they filmed the 2011 Dream House.
Both Weisz and Craig were in other relationships at the time but their chemistry must've been strong because the couple were married in New York in June 2011.
BLAKE LIVELY AND RYAN REYNOLDS
Reynolds and Lively were smitten with each other in Green Lantern and married a year later.
At least some good came out of box office sci-fi misfire Green Lantern.
Married in 2012, the pair met on the set of the comic book adaptation and now have a genetically-blessed baby girl.
Although the couple undeniably hit it off on set, the romance didn't start straight away.
Reynolds was married to Scarlett Johansson and Lively was dating Leonardo DiCaprio at the time but both of those relationships ended less than a year later.
It shouldn't come as a shock to fans of the show that at least one couple from True Blood fell in love. The vampire show was one of the raunchiest shows at the time, full of nudity and sex.
Paquin and Moyer started dating early on in the seven season show and wed in 2010.
The couple now have three-year-old twins and Moyer declared in a 2015 episode of Watch What Happens Live that it didn't take long for him to fall in love with Paquin.
"By day three or four (of filming) - oh, this is going to sound so syrupy - but I knew I wanted to spend the rest of my life with her. It was within seconds, really, and it just became a thing," he said.
MILA KUNIS AND ASHTON KUTCHER
The story of their real-life relationship is so romantic it could be made into its own movie.
Starring together on That 70s Show from 1998, Kunis told W Magazine she had her first ever kiss with Kutcher in one episode and in another they went to prom together.
Jump to almost 20 years later and the inseparable couple are now married and have a baby girl.
"We all get movie star crushes," she said. "I'm marrying mine."
TOM CRUISE AND NICOLE KIDMAN
Tom Cruise is known for acting with such intensity many of his female co-stars have admitted to falling in love with him.
We know this one didn't work out for the best but the first to fall head over heels was Nicole Kidman.
The vertically challenged Cruise met taller than average Kidman on the 1990 film Days Of Thunder. The couple adopted two children however their 10-year marriage ended in divorce.
More or less straight after his divorce from Kidman, Cruise met Penélope Cruz on the 2001 film Vanilla Sky. The couple dated for a number of years before he met Katie Holmes in 2005 which would also eventually end in divorce.
