(Cover) - EN Showbiz - Brad Pitt says meeting Angelina Jolie on the set of Mr. & Mrs. Smith was "a great collaboration" that transformed into a "greater collaboration".

The Hollywood couple met on set of the 2005 romantic action comedy. Brad was married to Jennifer Aniston at the time, and although he denied claims of adultery he later admitted he "fell in love" with Angelina while filming.

Brad and Angelina have since been inseparable and bring up six children together - Maddox, ten, Pax, seven, Zahara, six, Shiloh, five, and three-year-old twins Knox and Vivienne.

The 47-year-old hunk says meeting his gorgeous partner while filming was the beginning of a solid relationship.

"We had some good workshops beforehand. Had some good laughs and ideas. That was just a great collaboration that turned into a greater collaboration," he explained in an interview with Entertainment Weekly.

Brad would like to film more movies with Angelina, 36. The star says collaborating on further projects would allow the couple to spend more time together as a family.

"We should be doing them together," he said.

"That's what we should be doing. We should be doing everything together, and then we could work less. We could have more time off."

Brad starred in 1994's Interview with The Vampire: The Vampire Chronicles. The American actor responded to the interviewer's claim that he looked miserable throughout the horror film.

"I am miserable. Six months in the f**king dark. Contact lenses, make-up, I'm playing the b***h role" he replied.

The movie was filmed in London against a dreary backdrop. Brad said the depressive set affected him tremendously.

"One day, it broke me I called David Geffen, who was a producer I said, David, I can't do this anymore. I can't do it. How much will it take to get me out?' And he goes, very calmly, 40 million dollars,'" he chimed. (C) Cover Media
