The 45-year-old actor got himself into a bit of a scrape while wearing his superhero costume, which includes long, metal blades extending from his hands, on the set of 'X-Men: Days of Future Past' when he tried to cover up his manhood from female crew members.
He said: "There was a very intense first scene and I insisted on a closed set. I ran round the corner and all the female members of the crew were gathered there. I tried to cover myself and cut my inner thigh - it was just the inner thigh thankfully! The metal claws had to go - you can't have bits and pieces flying off."
The star made the comment during his appearance on tonight's (02.05.14) episode of 'The Graham Norton Show', where his co-star Michael Fassbender praised Hugh's commitment to his gym routine and admitted his energy was infectious.
Michael said: "His discipline is incredible - he is up and in the gym at 4.30 in the morning, every morning. When we arrived there was a 'Jackman' effect and we all started training to try and keep up."
Hugh spent 18 months in total toning up for his most recent stint as mutant Marvel Comics hero Wolverine, who possesses animal-keen senses and a capacity to heal quickly.
