Stars pay tribute to Pollack

George Clooney has led the tributes to his 'Michael Clayton' co-star Sydney Pollack, branding the actor/director a "class act".

Pollack died aged 73 on Monday, after a nine-month battle with cancer at his home in Pacific Palisades, Los Angeles.

The Oscar-winning star recently directed and starred alongside Clooney in 2007's 'Michael Clayton'.

"Sydney made the world a little better, movies a little better and even dinner a little better," says Clooney. "A tip of the hat to a class act. He'll be missed terribly."

Actress Sally Field - who starred in Pollack's 1981 movie 'Absence of Malice' - has also paid tribute to the star.

"Having the opportunity to know Sydney and work with him was a great gift in my life," she said. "He was a good friend and a phenomenal director and I will cherish every moment that I ever spent with him."

Pollack won two Academy Awards for the 1985 movie 'Out of Africa' - Best Picture and Best Director.
