Long careers are rarer than they look, and Julieta Serrano has become a familiar face who has seen the business change around her more than once. Very few actresses keep finding work for 61 years. Old Jacinta in 'Pain and Glory' is the role that outgrew the rest. There is 'Parallel Mothers' as well. The first credits arrived long before the title most people know. Drama is where the largest part of the work sits.
