Reese Witherspoon pretended to be Arnold Schwarzenegger in her new film.
The 33-year-old actress – who plays a 49ft superhero in animated movie “Monsters vs. Aliens” – made her voice so deep and macho much her children Ava, nine, and Deacon, five, didn’t even realize it was her.
She said: “They wanted me to sound like Arnold Schwarzenegger or Bruce Willis. I was like, how do you do that?!”
“The voice got deeper and stronger and they wanted me to be like an action hero. They had to coach me a lot.”
“We got home from seeing the movie for the first time and Ava and Deacon were like, ‘Do the voice! Is it really you?’”
In the new Dreamworks film, Reese plays Susan, an ordinary woman who gets hit by a meteorite and becomes Ginormica.
Reese loved the role so much, she bought her children dozens of Ginormica action figures.
She added to US TV show “Access Hollywood”: “I have all the action figures. As soon as I saw my own action figure, I ripped her out of the box and started playing with her. My kids love it, every morning we play with them. I have to pretend to be a giant robot.”
