Matthew Vaughn: Jennifer Lawrence is a great actress
Lawrence takes on the role of Raven Darkholme/Mystique in upcoming X- Men: First Class.
The film, which is set to be released in the UK on June 2nd, also stars James McAvoy, Michael Fassbender and Rose Byrne.
Vaughn directed the film and said that he thought Lawrence was the right actress for her role.
"There are a lot of young American actors right now who haven't got any technique," he explained, noting that many think that if they are good looking they'll get work.
"I needed someone who could act," he added.
Lawrence, who previously starred in The Burning Plain and The Poke House, was nominated for the best actress Oscar for 2010's Winter's Bone.
The film, which also starred John Hawkes and Garret Dillahunt, told the story of a young girl on the hunt for her drug-dealing father.
