London: Actress Meryl Streep believes young actors are often intimidated by her until she forgets her lines while delivering a dialogue.

The 62-year-old said her younger co-stars soon relax when they realise she is just as prone to making mistakes as anyone else, reported a leading daily.

"I do feel that thing when a young actor comes in. I feel an obstruction. It's an invisible thing that pulsates in the room. You have to puncture it and get rid of it before you can start working. Usually the first time I forget my lines, which happens a lot lately, everybody relaxes. Everybody goes, 'Oh, she's not so great," Streep said.

The 'Iron Lady' star also said she feels sorry for younger actresses as the roles available to them are not as interesting as the ones she gets offered.

Streep added,"From 'The Devil Wears Prada' to 'Mamma Mia!', it's been a pretty wide variety of things. Maybe that's because they don't know what to do with me. It's really fun. I feel sorry for the young girls because those parts are cookie-cutter. One after another, indistinguishable."
