Ah, romance. It’s part of the reason moviegoers flood the theaters every single week. It’s easy to get lost in the on-screen chemistry between two heavily-trained actors. With all that believability going on, it’s even easier to forget just how big of an age difference there is between the two love interests.

We did some research and what we found just may shock your pants off! Here’s a collection of some of the largest romantic age gaps in the world of cinema. Enjoy…

1. Brad Pitt and Rose Byrne: 16 Years
These two box office phenoms starred alongside each other in the 2004 film, Troy. It’s always hard to gauge how old Brad Pitt is — that dude is friggin’ ageless!

2. Sean Penn and Emma Stone: 29 years
Gangster Squad was the film that brought these two together as lovers on-screen. Crazy how a little makeup, and a touch of CGI here and there, can almost make them look like a believable couple!

3. Johnny Depp and Amber Heard: 23 Years
In 2011, Johnny first met Amber while filming The Rum Diary, wherein they play love interests. Though their relationship in real life didn’t quite work out, they can always look back on this film fondly. (Or, maybe not…)

Whoa!
So, you mean to tell me there were over two decades separating Johnny and Amber? That seems crazy! If this is only the beginning, I can only imagine how much bigger these age gaps get…

4. Richard Gere and Winona Ryder: 22 Years
Autumn in New York, the touching film starring these two legends, was a real tear-jerker when it hit theaters back in 2000. Looks like neither of them have aged a bit since. Way to go!

5. Jennifer Lawrence and Bradley Cooper: 16 Years
Wait… what?! I would’ve thought these two were in the same high school class — not nearly 20 years apart! Not sure how he does it, but Bradley Cooper will always look like he just graduated.

Forever young?!
What is their secret?! How are these actors able to appear and act so youthful on camera?! Did they just collectively agree to stop having birthdays?! I need some answers here, people…

6. Woody Allen and Juliette Lewis: 37 years
The startling large age gap was pretty obvious in Woody Allen’s 1992 motion picture, Husbands and Wives.

7. Emily Blunt and Tom Cruise: 20 Years
The heart-racing thriller from 2014, Edge of Tomorrow, was what brought these two together. At this point in his career, I think it’s safe to assume that Tom’s going to be at least 20 years older than his co-star, right

8. Harrison Ford and Anne Heche: 26 Years
Their movie, Six Days, Seven Nights, was all about numbers and so is this list! Even though they look relatively in the same age bracket, Han Solo is dang-near 30 years older than his love interest in this film. Wow!

9. Margot Robbie and Leonardo DiCaprio: 16 years
The Wolf of Wall Street was an instant classic as soon as it hit cinemas across the country. No matter how old he gets, Leo will always be that young kid standing at the end of that big ol’ boat. Never grow up, Leo. Never grow up…

10. Billy Bob Thornton and Scarlett Johansson: 30 years
These two starred in The Man Who Wasn’t There, but you know who did show up? Their HUGE age difference? 30 years?! That’s a whole lot of birthdays, party people…

11. Keira Knightley and Steve Carell: 22 Years
With as lovable as these two are, it’s almost inherent to ignore their difference in age. Honestly, these two would make an insanely adorable couple in real life. What a shame…

12. Liam Neeson and Olivia Wilde: 32 years
In 2013, the film Third Person came out and audiences were treated with a surprising on-screen relationship. Though they’re years apart from one another, you can tell they have a lot in common.

13. Sean Connery and Catherine Zeta-Jones: 39 years
Even when Entrapment came out, audiences everywhere couldn’t help but notice the massive difference in age between the two leads. However, with Catherine Zeta-Jones married to Michael Douglas (who’s 25 years older than her) it didn’t seem that far-fetched.

Well, well, well…
That certainly was an eye-opening list of cinematic romance, wouldn’t you say? Who knew there were so many years between these famous motion picture couples? I wonder what crazy lovable combos Hollywood will come out with in the future…
