Sidney Livingstone has been in the trade long enough to be called a veteran actor who has seen the business change around him more than once. Drama is where the largest part of the work sits. The filmography runs to some 38 credits between film and television. Park Keeper in 'About a Boy' is the role that outgrew the rest. Among the rest of the work, 'Lifeforce' stands out. Viewing habits have changed more than once since the first credit.
