Jennifer Lawrence has been left with blister scars from X-Men: First Class.
The 20-year-old actress said that the eight-hour process of being shaved, rubbed down with alcohol, coated with five layers of paint and topped with silicone scales to play blue-skinned mutant Mystique has scarred her décolletage (the upper parts of a woman's breasts).
She said in an interview with The Telegraph: "I got tired just thinking about it. It was a long process. I have scars."
With a budget of $120 million, shooting the X-Men prequel was more intensive than Winter's Bone - the film for which Lawrence received an Oscar nomination for Best Actress.
She said: "There are so many production jobs - three times as many as there were on Winter's Bone."
In spite of the ordeal of being transformed into Mystique, Lawrence said that filming X-Men: First Class was "a very cool thing to be a part of".
"It was mostly just fun. I don't remember us working, I just remember us cracking up on set."
X-Men: First Class opens in New Zealand on June 2.
