Leslie Mann has described the first time that she saw ParaNorman as 'mind-blowing'.
The actress has lent her voice to the new animation movie, which is directed by Chris Butler and Sam Fell.
And Mann admits that it was great to see all of the elements of the film come together.
Speaking to Deadline the actress said: "It was fun to see how much work goes into these characters... to see the finished product was just mind-blowing.
"It's so awesome to watch and I was scared, because I'm a scaredy cat and I believe in all that stuff, I believe in ghosts... It's fun scary."
An all star voice cast has been assembled for the movie as Mann has worked alongside Kodi Smit-McPhee, Anna Kendrick, Casey Affleck and Christopher Mintz-Plasse.
But as well as hearing her voice in ParaNorman we are also going to be seeing Mann in This Is 40, which is a spin off movie from Knocked Up.
ParaNorman is released 14th September.
