Alfonso Cuaron has won best director at tonight's Oscar ceremony.
The 52-year-old director has picked up the coveted statuette for his film Gravity.
Gravity, a deep space thriller starring George Clooney and Sandra Bullock, followed veteran astronaut Matt Kowalski and Dr. Ryan Stone, a medical engineer on her first space mission, as their space shuttle is hit by debris and loses contact with Earth.
Cuaron beat off competition from American Hustle's David O Russell, Nebraska's Alexander Payne, 12 Years a Slave's Steve McQueen and The Wolf of Wall Street director Martin Scorsese to win the best director category.
Picking up the prestigious prize, the Mexico City-born film-maker called the film a "transformative experience," joking that, "what really sucks is that while for a lot of people that transofrmation was widsom, for me it was just the colour of my hair."
Cuaron went on to thank his "amazing son and co-writer" as well as the film's stars George Clooney and Sandra Bullock. To Bullock, he said: "Sandy, you're Gravity. You're the soul and heart of this film."
Gravity was nominated for 10 awards at tonight's Oscars ceremony, including best picture.
