EXCLUSIVE: Ryan Reynolds Reveals Most Romantic Thing He's Done For Blake Lively, Says She's Seen 'Deadpool' Se

The star opens up to ET about his romantic side, and explains why 'Deadpool' is the perfect Valentine's Day date movie.

Ryan Reynolds is gearing up for the release of his new film, Deadpool, which comes out Valentine's Day weekend. While you might not equate the murderous, profane mercenary with love and happiness, that doesn't mean that Reynolds isn't a soft-hearted romantic off-screen.

The 39-year-old actor spoke with ET at a fan screening of Deadpool at AMC Empire Theatre in New York City, where he revealed the most romantic thing he's ever done for his wife, Blake Lively.

"I've done things where I've like flown halfway across the world to just see my wife for a day," he shared, "because you’ve got to do that."

Reynolds admitted that he hasn’t been able to do much planning for this Valentine’s Day, however.

"I've been in about 15 countries in 20 days," he explained. "But I will come up with something spectacular."

Although it doesn't look like Reynolds needs to pull off anything too elaborate. At the screening, Lively walked the red carpet with her handsome hubby and the two couldn't have looked more in love.

As for Deadpool, Reynolds promised that high-energy action flick is also "romantic." "It's like borderline The Notebook 2, so be ready for that," he teased.

What the movie definitely has is a sex montage, and Reynolds told ET that his wife has already seen it.

"She knows as well as I do that these scenes are never sexy to film, they just look sexy in the movie," he said.

The film has been something of a passion project for the star, who’s been promoting the cheeky, R-rated superhero spectacular for months. He was also instrumental in getting the film financed and created in the first place.

Reynolds admitted that he sees a lot of himself in his foul-mouth, sharp-tongued character, sharing, "Deadpool and I definitely share a beating heart."

The film, which balances action and intense violence with light-hearted pop-culture references, takes a few jabs at other real-life celebs, including David Beckham and Hugh Jackman, but Reynolds says the stars will take the swipes in stride.

"Hugh Jackman is a very good friend of mine, and a real sport. And I don't know Mr. Beckham as well, I've met him, but I know that he also is a great sport," Reynolds explained, "and nobody gets it worse than me, so let that be known."

Reynolds is clearly excited for the film to finally hit the big screen, and he even recently made a fan’s day just ahead of its premiere.

When a young woman named Mariah Boyle got her wisdom teeth taken out, she woke up after being under anesthetic and was under the impression that she somehow missed Deadpool's time in theaters, making her totally inconsolable.

Boyle's tearful, groggy freak out was filmed by her mom and posted to Facebook, and it wasn't long before Reynolds responded to the fan with a pic and some free tickets.

"Mariah Boyle, am I the only one who thinks the tooth fairy is a giant f***ing stalker?" Reynolds wrote beneath a photo of himself with cotton balls stuffed in his mouth. "I mean seriously, who leaves two tickets to the Deadpool premiere under your pillow?"

You have to appreciate that level of fan service.
