Julia gives a 5 star performance as earthy Erin Brockovich, a woman committed to improving her life and those of her local community against the corruption of big business. It's a familiar theme but well handled by director Steven Soderberg, underplaying the obvious self- consciousness of Julia's transition from glamour queen to dramatic actress.
