Film star Michael Douglas is to undergo chemotherapy for throat cancer, according to reports in the United States.

The Oscar-winning actor, 65, who has a home in Warwick, will receive eight weeks of radiation and chemotherapy treatment, People magazine reported.

Reports say he is expected to make a full recovery and he is quoted saying: "I am very optimistic."

Mr. Douglas, whose mother Diana is from Devonshire, has starred in or produced more than three dozen films in a career spanning four decade, including Wall Street and Fatal Attraction. In September, he will appear in Money Never Sleeps, the Wall Street sequel by Oliver Stone.

He has two children, aged ten and seven, with wife Catherine Zeta-Jones, and a 32-year-old son from a previous marriage.
