Zac Efron Has Fans A Bit Concerned After 'The Iron Claw' Set Pics Surface

The first pics of Zac Efron on the set of his new movie, The Iron Claw, have surfaced.

In the images, via The Daily Mail, the 35-year-old actor is shirtless and wearing a long wig as he heads to the set from his trailer, with just a towel wrapped around his waist.

Based on the true story of the Von Erichs, The Iron Claw follows the rise and fall of the Von Erich family, a dynasty of wrestlers who made a huge impact on the sport from the 1960s to the present day.

After the images surfaced, many have expressed concern for Zac after he opened up about what happened the last time he beefed up for a role.
