Actress Sienna Miller tonight said she was doing her best to "go green" by switching off her phone charger and plug sockets and supporting carbon-neutral schemes.

The British star was showing off her environmental credentials at the UK premiere of Factory Girl, in which she plays Andy Warhol's muse Edie Sedgwick.

The movie is a biopic of the 1960s It-girl and fixture on the New York party scene, who died of a drugs overdose in 1971 aged 28.

"I switch off my plug sockets at night and turn my phone charger off. I'm a great supporter of carbon-neutral," the star said.

The premiere is taking place this evening at the Vue Leicester Square cinema.

With her tumultuous love life usually splashed all over the newspapers, it was probably a relief for Miller to arrive arm in arm with her older sister Savannah.

Miller, 25, raised eyebrows at the New York premiere in January when she turned up to the after-party in a pair of black pants.

She later explained the outfit was a homage to Sedgwick.

Miller also admitted to loving her food.

Director George Hickenlooper joked that he had tried to stop Miller tucking into French fries and chocolate during filming but she simply told him to "bugger off".

Miller said: "He used to steal my bagels. He gave up because I love my food."

The actress said the premiere was "very exciting, it feels like a good party after lots of hard work."

She said she had enjoyed playing her first lead role: "You try to lose yourself in the moment."

And she praised co-star Guy Pearce, who plays iconic pop artist Andy Warhol, saying: "Guy Pearce is a great actor, a great friend and totally embodied Andy."

Miller wore a vintage cream and black Balenciaga mini dress, black tights and black Sergio Rossi shows as she walked down the shocking pink carpet outside London's Vue Leicester Square cinema.

Her sister wore a grey dress from 2812, their clothing label due in shops from July.

Hickenlooper said he was thrilled that hundreds of people turned out to the premiere.

"I'm so flattered all these fans are here," he said. "I like the British, it's a more literary climate so maybe they will appreciate the film more."

Among the famous faces who turned out to support Miller was actor Rhys Ifans who said he had seen the film and added: "She was amazing. It's a marvellous transformation and she's in the knack (nude) so you can't go wrong."

Critics in the US have given the film mixed reviews.

Industry bible Variety described Miller's portrayal as "ultimately too whiny and narrowly focused to be a genuinely tragic figure" while the Los Angeles Times called the biopic "superficial".

The film attracted controversy with its depiction of a doomed affair between Sedgwick and a musician, played by Hayden Christensen, and Miller has dismissed rumours that the sex scenes between her and Christensen were genuine.

Singer Bob Dylan is reportedly unhappy about the musician character, believing it is based on him and the film falsely blames him for Sedgwick's death.
