Director Jake Scott has described Kirsten Stewart as 'wolfish'.
The pair work together on new movie Welcome To The Rileys, which also stars James Ganddolfini and Melissa Leo, and Scott admits that working with the Twilight star could be a little difficult.
Speaking to E! Online the director said: "She's very vulpine - very wolfish - and wily, kind of twitchy," he said. "Directing her is kind of like wrangling a herd of cats."
"Kristen, more than anyone, would go off-script or off-course, but it would be brilliant and it would work. But it would throw [Welcome To The Rileys costars] Jim [Gandolfini] and Melissa [Leo]."
The director also revealed that the actress wants to be taken seriously in the industry: "[Kristen's] been playing this same character in - what - two or three movies now, and that frustrates her.
"She wants to be taken seriously as an actress - and the crazy thing is, before Twilight, she was doing that kind of work... She's very proud of her work in this movie."
