The chemistry between actors is easily manipulated by the skill of those playing the roles of his and hers. A kiss can say a thousand words, and when it is between two people who are a couple both on-and-off-screen, it’s hard to deny the energy that projects from the inherent love. There have been plenty of couples like Brad Pitt and Angelina Jolie inMr. and Mrs. Smithor Zac Efron and Vanessa Hudgens fromHigh School Musicalwho have blazed a trail for natural chemistry in their respective films.
Though some couplesmay have broken upsince the release of their movie together, the bonds of those who fell for one another on screen are worth the chatter, as their combined energy undoubtedly made their films that much better.

Channing Tatum and Jenna Dewan
ThoughChanning TatumandJenna Dewanhave since broken up, their connection in the 2006Step Upfilm is undeniable. The closeness between the two as they dance with one another is so natural, you forget there’s production in the background. The two met during filming and progressed their relationship into marriage just three years later in 2009. In 2013 the pair welcomed their first child together. Though the two would separate in 2018, their dance scenes are heavily influenced by natural emotion.
From the very beginning ofStep Up,where Tatum’s Tyler and Dewan’s Nora meet after Tyler is probated by law to serve the community with hours at the local performing arts school, to their very last dance showcasing their absurd skill, the two demonstrated a crush-like energy that manifested into an entire family off-screen. Both have since moved on to other relationships, but continue to support the other through co-parenting and more.

Ashton Kutcher and Mila Kunis
Ashton KutcherandMila Kunisboth made a name for themselves in the entertainment industry all the way back in 1998 onThat ‘70s Show.The comedic series follows a group of cheeky teenagers who have each other’s backs through anything and display a closeness that’s unlike any other group of friends. Michael (also known as Kelso), played by Kutcher, and Jackie, played by Kunis, form a relationship that followed them off-screen all the way into a 2015 marriage—and quite honestly, we foresee no reason for a breakup of any kind.
Ashton and Mila began dating off-air in 2012 from a bond that manifested deeply through laughter and genuine friendship while filming. The two shared intimate scenes on the show and actually,Ashton was Mila’s first kiss. Though Kutcher felt their age gap at the time was more like a brother and sister relationship rather than a romantic one, the pair grew close as the years progressed.

They now have two beautiful children and continue to work together on films like the 2014Anniemovie and appear in the new Netflix spinoffThat 90s Show.
