Zac Efron Working A White Tank Top On ‘Paperboy’ Set [PHOTOS]

Zac Efron was back on the set of the Paperboy today, and lucky for us he was just wearing a tank top (and obviously pants). He sure does love showing off his biceps.

Co-stars Matthew McConaughey and Nicole Kidman were nowhere to be seen.

Directed by Lee Daniels, the thriller follows an idealistic Miami reporter as he returns to his Florida hometown to investigate the possibly unlawful imprisonment of a death-row inmate.
