Zac Efron really is all grown up.

The former High School Musical actor will anchor his most mature movie to date in 2012, starring alongside Nicole Kidman, Matthew McConaughey, John Cusack and others in The Paperboy, an upcoming drama based on a 1995 novel by Pete Dexter.

The film focuses on a Miami Times reporter who comes back to his Florida hometown to investigate a case involving a death row inmate. It's not the only film to star Efron in the new year, either.
