Simon Pegg has shown off a new physique after a six-month body transformation for his new film Inheritance.
In a shirtless photo, the Run Fatboy Run star can be seen smiling while looking away from the camera, showing off a lean but muscular torso with tattoos dotted over his shoulders and upper chest.
A post from his personal trainer Nick Lower said: "#SimonPegg 6 month body transformation for #InheritanceMovie.
"The brief for this role was lean, VERY lean. It required a specific body shape & look."
The tweet was shared on Pegg's official Twitter page, with a comment adding: "And occasional grumpiness."
