"Eight out of ten women believe that the first kiss will tell them everything they need to know about the relationship" -- that’s where Hitch comes in.

It’s hard to believe it's been ten years since we first learned the rules of dating. Back in 2005, ET’s Kevin Frazier had the terrible assignment of flying to Hawaii to sip tropical drinks with the film’s stars, including Will Smith, Kevin James, and Eva Mendes.

"I was trying to create the comedy in a way that it would be strong, and powerful, and still funny – but not getting tender with it," Smith told ET.

The rom-com had some hilarious moments, like Eva Mendes getting kicked in the head on a jet ski, a stunt she did on her own.

"It was actually my first real stunt in water," said Mendes. "It was a lot of fun!"

The infamous allergic reaction scene was inspired by Smith’s real-life reaction to bee stings.

"When I get stung, that's how I look," said Smith. "That was taken from pretty much an actual picture of what happens to me."

And we can’t forget the infamous James and Smith lip lock!

"I didn't kiss a guy. I kissed Will Smith -- there's a big difference," said James. "I get it now. I understand what all the hype is about."
