Aniston can't fake chemistry with co-stars

New Delhi (ANI): Actress Jennifer Aniston has admitted that she finds it hard to fake chemistry with her co-stars. The former 'Friends' star - who has starred alongside some of Hollywood''s biggest male stars, including Clive Owen, Vince Vaughn and Owen Wilson, believes that it is extremely important for the two main characters of a film to connect.

However, she also admitted that bringing on-screen chemistry isn't that easy. "You can't buy chemistry. You can't train it. On the first day of rehearsal it's like, 'This is good.' You know it when it happens and boy do you know it when it's not there," she added.

Meanwhile, the 40-year-old actress has revealed that she dreams of directing her own movies. "I'm still working on becoming a director. I''m just waiting for the right thing. When you get to a place in your career where you're like, 'OK, I feel like I can breathe and I can make some choices that creatively stimulate me.' I don't know if acting is always going to be it, but I love it," she said.
