James Franco is up to his old tricks again.

The Hollywood star, who’s known for his revealing selfies on Instagram, is starring in new HBO series The Deuce.

The show chronicles the rise of the porn industry in the 70s, and as expected from a show about adult films, Franco – who plays identical twins – strips off for the role.

In one scene, the star shows off his bum, and it looks as though he cut back on the manscaping so he could look even more authentically 70s – see what we mean below:

The Deuce will debut on HBO on September 8 in the US. There’s currently no word on a UK air date.
