UPDATE: Kate Winslet confirmed to play Vivienne Westwood in biopic
"The script is going well and Kate will play Vivienne," a spokesperson said. "It has been a long time in the planning but we're very excited that it's happening."
Once a script has been finalised, Winslet is expected to spend time with Dame Westwood, in order to get the most out of her performance. The film is said to follow the designer's success from her punk days to now.
