FLASHBACK: Brad Pitt and Angelina Jolie Sizzled On- and Off-Screen in 'Mr. & Mrs. Smith'

It’s been 10 years since Brad Pitt and Angelina Jolie shared the big screen in Mr. & Mrs. Smith, and ET is flashing back to the controversial start of the couple’s steamy relationship.

The pair played opposing assassins undercover as a boring suburban couple in the 2005 film, and their chemistry was obvious in the film’s steamy fight and dance scenes.

“It’s the discovery of two strangers,” Jolie told ET at the time. “It’s all the heat and passion of a stranger, somebody that excites you, and discovering each others’ bodies and trying to resist.”

Pitt, who was still married to Jennifer Aniston back then, downplayed the steamy scenes when promoting the film.

“There’s not much of a love scene in there,” he told ET, trying to quickly move on from the question. “I know you want to make something out of it, but there’s really not.”

Jolie was less cagey with her answer, telling ET at the film’s premiere, “There’s no sex without danger.”

Pitt and Jolie, who are now parents to six kids, finally tied the knot last August, and took something of an unconventional honeymoon, playing a “couple on the brink of disaster” in By the Sea, which Jolie also wrote and directed.

“It's an odd honeymoon,” Jolie admitted at the film’s premiere at AFI Fest last week. “A few weeks into it, we wondered if it was a good idea because it is ... heavy and it's a lot of fighting. But we had the thought that if we can do it, if we can be close in that way and that open as artists, then you push through and you really get closer and you learn something.”

“If it doesn't work it's the worst honeymoon ever,” she added with a laugh, “but if it works you've learned something and I think that's how we came out of it stronger.”

“It was a good time,” Pitt agreed. “We came out stronger on the other end. Just, making something together, and something she wrote, it was a real pleasure.”

Some couples might have a hard time transitioning their personal relationship to a professional one, but Pitt said having his wife helm the film was “no different” than working with any other director.

“She knows when I'm faking it better than anyone else, but, you know, the actor/director relationship is a very collaborative experience,” he explained. “It's really no different, and actually a great pleasure, ‘cause you’ve got to trust your director. Who do I trust more than my wife?”
