Efron arrived for the red carpet screening with fellow British casting mate, David Oyelowo, and director Lee Daniels, who previously brought audiences the award-winning film "Precious" to big screens.
Based on the 1995 novel with the same title, "The Paperboy" tells the story of a reporter who returns to their Florida hometown to investigate a case involving of a death row inmate.
In the film adaptation, Matthew McConaughey plays the reporter, Ward James. Efron stars as James' younger brother, as the two men continue to investigate events surrounding a murder to exonerate the inmate on death row, who is played by John Cusack.
More big Hollywood names starring in the movie include Nicole Kidman and Macy Gray. Britain sensation David Oyelowo, who also attended the premiere, plays Yardley Acheman, another central character in Peter Dexter's noir-ish crime novel.
Movie goers who may be familiar with Efron's former innocent, Disney-like image, be warned, caution film reviewers, as the "The Paperboy" reportedly airs some wild scenes, including one where Efron is supposedly "peed on" after a jellyfish sting.
