Workplace romances aren't uncommon, but when audiences are literally paying to watch their sparks fly on the silver screen, it becomes a Hollywood love story on a whole new level.
Sadly, not every cinematic romance has the kind of staying power that results in living happily ever after. And while the following list of nine resilient power couples — still together as of press time, as far as we know — is far from comprehensive, their transcendent relationships remain notable all the same. Their highlighted movies are listed in reverse-chronological order.
Angelina Jolie and Brad Pitt, "By the Sea" (2015)
With a recent trailer teasing a November release, "By the Sea" marks Jolie and Pitt's latest cinematic collaboration, but no one could deny the sparks that famously flew when they played married assassins in 2005's "Mr. and Mrs. Smith." They went public with their relationship after the release of that movie, and married in 2014.
Kristen Bell and Dax Shepard, "Hit and Run" (2012)
Off-screen, the two had already been a couple when they appeared in the 2010 rom-com "When in Rome," but in that movie, Bell appeared to show little interest in Shepard's advances, despite lines like "Can someone call the vet? Because these puppies are sick!" As significant others in "Hit and Run," their relationship is tested as Shepard's criminal past comes back to haunt him. Married in 2013, Bell and Shepard's real-life relationship seems to be less of a "Hit and Run" and more like cruise control (in the best way), even if their memories of Bell's delivery-room experiences differ dramatically.
Blake Lively and Ryan Reynolds, "Green Lantern" (2011)
The critical reception to this comic-book adaptation may not be the stuff of legend, but one thing that's had a more lasting impact is the bond between the romantic leads, who welcomed daughter James in late 2014.
Anna Faris and Chris Pratt, "Take Me Home Tonight" (2011)
In the coming-of-age movie set in the '80s, the pair gets engaged at a house party for the ages, but Faris' Wendy later gets cold feet. (Thankfully, the real-life couple actually made it to their own wedding in 2009.) And if playing exes in a movie counts toward this list, they've got that covered, too: Also released in 2011, the comedy "What's Your Number?" stars Faris as Ally Darling, who's coping with drama surrounding a variety of ex-boyfriends — including Pratt's character, Disgusting Donald.
Jenna Dewan and Channing Tatum, "Step Up" (2006)
During a June Q&A with Reddit users, Tatum originally said "Magic Mike" is his favorite movie in which he appears, then changed his answer to the PG-13 dance flick — for obvious reasons. "[It's] 'Step Up.' Where I met my wife," replied Tatum, who married Dewan in 2009. "Because if I don't say that my wife will kill me."
Jada Pinkett Smith and Will Smith, "Ali" (2001)
Meeting on the set of the '90s NBC sitcom "The Fresh Prince of Bel-Air," the Smiths got "Hitch"-ed in 1997, but didn't share a cinematic screen kiss until they co-starred in "Ali" years later. Will played the legendary boxing champ and activist, Muhammad Ali, and Jada portrayed the boxer's first wife, Sonji Roi.
Christine Taylor and Ben Stiller, "Zoolander" (2001)
In the fashion-forward flick, Stiller's preening title character wins the heart of Taylor's reporter character, but since their real-life wedding in May 2000, their relationship appears to have been just as much of a model.
Annette Bening and Warren Beatty, "Love Affair" (1994)
The remake of the romantic drama — chronicling lovers who have an affair and talk of reuniting after they part ways — stars two Academy Award winners whose relationship has remained intact ever since. Their chemistry can be traced back to their work on the 1991 biopic "Bugsy," in which Bening played the love interest of Beatty's mobster title character.
Goldie Hawn and Kurt Russell, "Overboard" (1987)
Meeting while filming 1984's "Swing Shift," Hawn and Russell's relationship proved to have sea legs long after the release of this madcap nautical comedy, whose requisite ensuing hilarity occurs when Hawn's character falls off a boat and has a bout with amnesia.
