Bob Hoskins's career has spanned 4 decades

Bob Hoskins has announced that he's to retire from acting after being diagnosed with Parkinson's Disease.

The 69-year-old, who plays a dwarf in Kristen Stewart's film Snow White And The Huntsman, discovered he was suffering from the incurable condition in autumn but has only now decided to reveal the news publicly.

'He wishes to thank all the great and brilliant people he has worked with over the years, and all of his fans who have supported him during a wonderful career,' reads a statement.

'Bob is now looking forward to his retirement with his family, and would greatly appreciate that his privacy be respected at this time.'

Bob began acting in the 1960s but his breakthrough came when he starred opposite Helen Mirren in gangster film The Long Good Friday in 1980.

He's arguably best known for his Golden Globe-nominated performance as Eddie Valiant in 1988 film Who Framed Roger Rabbit.

In 2010, he won an International Emmy for his role in BBC drama The Street.

Other famous faces who suffer from Parkinson's - which is a progressive condition that causes tremors, rigidity and slowness of movement - include Michael J Fox and Muhammad Ali.
