Kate Winslet may have caused her own little chaos at Kensington Odeon tonight as fans rushed to get a glimpse of the actress who was dressed in a midnight blue body-hugging number with a dangerously plunging neckline.

The Oscar-winning actress attended the premiere of A Little Chaos looking every inch the Hollywood superstar in her sophisticated Stella McCartney dress that featured a huge bow detail.

We can’t imagine one of Hollywood’s greatest stars being anything but confident, yet Kate had a startling confession to make.

She admitted she would not have been able to star in her latest film had she not managed to overcome her fear of the director – Alan Rickman.

Kate last worked with Alan when she was 19 on her second feature film Sense and Sensibilty. Her character Marianne married Rickman’s Colonel Brandon.

“It was wonderful to be part of something that was a collaboration with a friend and someone who I’ve known for such a long time,” she said of being directed by Alan in A Little Chaos. “Who I can’t believe, really, I managed to ever get over my fear of.

“When I first met Alan I was absolutely terrified.

“I was 19, he was Alan Rickman, and he’s got that voice, and I remember meeting him in the hair and make-up trailer and thinking, ‘I’m going to die. He thinks I’m rubbish. Why am I here?’.

“And here I am 20 years later having ended up marrying him in Sense and Sensibility and now being directed by him in A Little Chaos.”

Kate, who attended the premiere with co-stars Helen McCrory and Alan, plays Sabine De Barra, a fictional landscape gardener who overcomes the odds to design an ornate rockery in the elaborate gardens of Versailles for King Louis XIV (played by Alan).

The mother-of-three was pregnant with her third child at the time of filming, but still took part in a perilous stunt scene when her character falls into a weir.

She revealed: “Flinging myself into that water, I was pregnant and I deliberately didn’t tell anybody, because I knew they wouldn’t let me fall in if they knew. Of course I had to do that bit, so I did, and I had a great time.

“It was (freezing), but I’ve done Titanic, so it was a bit like taking a cold bath in comparison.”

Alan admitted recreating the Palace of Versailles on location in England on a shoestring budget had been a challenge.

He said: “The problem is England is a thin country, and you’re only ever about 20 miles from a motorway. Or the wind changes and you’re on a flight path. So we have many interesting out-takes.”

Asked if there was enough funding for the arts in Britain, Rickman replied: “Give me a break! I’ll come back and answer that question after the election.”

A Little Chaos, which also stars Matthias Schoenaerts, opens in cinemas on Friday April 17.
