Jessica Chastain will never date an actor again.

The 'Zero Dark Thirty' actress previously romanced a famous movie star during her time at The Juilliard School - New York's esteemed performing arts academy - but she spent the whole evening ''freaking out'' that the pair would be snapped by the paparazzi, so she has vowed never to repeat the experience.

She said: ''I have a rule. No actors. I have dated an actor before, at Juilliard, but since then, I've only been on a couple of dates with one and I was so freaked out someone was going to take a picture of us, because they were famous.''

The 35-year-old beauty finds it ''boring'' talking about her acting work with potential lovers, but she enjoys discussing films with boyfriends in the same way as a 15-year-old fan of big screen productions.

She added in an interview with Britain's InStyle magazine: ''I realised I wanted just to be able to hang out with someone ... And I didn't want to talk about the business, first of all.

''I love movies. But I love talking about them like when I was 15 years old.

''I'm a film fan, but I don't want to talk about auditions or what movie I'm gonna do. I find that so boring.''
