Breaking out on the WWF circuit in the mid-90s as the smack-talking "The Rock," Johnson eventually outgrew the ring and brought his talents to the big screen. The starring roles came immediately with sleeper hits such as "The Rundown" (2003) and "Walking Tall" (2004), and it wasn't long before the big blockbusters came calling.
