SINGAPORE - The serial killer Ted Bundy was a particularly successful predator because he blended into the mainstream so well. He was good-looking, gregarious and maintained a family life even as he left a trail of corpses across several states in the early 1970s.

Actor Zac Efron, who portrays Bundy in the biopic Extremely Wicked, Shockingly Evil And Vile, felt that his task was to show how skilled the mass murderer was in luring others, especially young women, to place their trust in him.
