Glenn Close at NBC Studios ahead of their appearance on 'Late Night with Conan O'Brien'. New York City, USA - 07.08.07

Close plays villainess Cruella De Vil in the children's movie and its sequel, 102 Dalmatians.

But the 60-year-old has realised impersonating De Vil's evil laugh in real life can terrify children.

She says, "I learned the hard way - a child came up to me and I thought I'd be Cruella. I looked just like my character (at the time).

"And I did the evil Cruella laugh, and the child burst out crying. I felt so awful."
