Marriage isn't perfect: Angelina Jolie

London: They are known to be one of the most compatible real-life couples but actress Angelina Jolie says says she and husband Brad Pitt "have (their) issues."

Jolie, however, added they are nothing like the unhappy couple they play in their upcoming film "By the Sea", reported Female First.

The 40-year-old actress has six children, Maddox, 14, Pax,

11, Zahara, 10, Shiloh, nine, and seven-year-old twins Knox and Vivienne, with Pitt, 51.

"Brad and I have our issues, but if the characters were even remotely close to our problems, we couldn't have made the film.

"This is the only film I've done that is completely based on my own crazy mind. As artists we wanted something that took us out of our comfort zones. Just being raw actors. It's not the safest idea. But life is short."
