Lord Richard Attenborough "was a force for good" who stuck with Chelsea Football Club through dark times, a statement from the club said.
He led a long and successful life and always found time for the things in life he loved most, one of which was Chelsea FC.
Renowned throughout the world for his work in cinema which honoured him with awards for acting, directing and producing, football - and Chelsea in particular - was never far from his thoughts.
His personality was woven into the tapestry of the club over seven decades. He was a consistent force for good at the club, even in dark times.
He will be greatly missed, and the thoughts of everyone at Chelsea FC are with his family and friends at this sad time.
