"Zac looks just like Ted Bundy".
The film is a dual portrait of Bundy and his longtime girlfriend Elizabeth Kloepfer (Lily Collins), the former's life told through the perspective of the latter up until the moment Bundy is strapped to the electric chair.
Extremely Wicked, Shockingly Evil and Vile is now seeking US distribution.
A trailer for the movie was recently released, but a scene where Efron takes his shirt off - revealing his. umm, well-sculpted body - left viewers concerned about the casting for the film.
The Guardian's Benjamin Lee awarded the film 3 stars and described Efron's portrayal of Bundy as "career-changing", "remarkably accomplished" and "fiercely committed".
On Rotten Tomatoes, the film - at the time of writing - holds a 65 per cent rating from 17 critic reviews, 11 fresh and six rotten.
The AV Club described Efron as "very good".
However, although it may be hard to believe given his horrific deeds, at the height of his infamy Bundy was often considered to be charming, charismatic and even good-looking.
Lee found the film "drab", and that there was little to grasp audiences other than Efron's performance.
In a nutshell: "The star's charismatic and creepy performance as the notorious serial killer is the best thing about an otherwise pedestrian and graceless drama". "You could just feel it. People really seem to be connecting and getting something out of it", filmmaker Joe Berlinger, who directed the new drama "Extremely Wicked, Shockingly Evil and Vile", said in an interview Sunday, after its premiere Saturday night and a second screening Sunday morning.
With the disturbing crimes of Ted Bundy already well-publicized, we (almost) never see any of his gruesome exploits on screen.
Vulture, though a fan of Efron's performance, did not like the film.
John Henry Browne, who served as Bundy's lawyer in the '70s and '80s, previously shared with TMZ that Efron's charisma could effectively recreate what were components in Bundy's coercion of his victims, but Browne claims that the true test will be if Efron can capture Bundy's "essence of evilness". Oh and Metallica frontman James Hetfield as a police officer for some reason.
