The actress’ children wanted so much for her to sound like a big action hero in her new movie “Monsters vs. Aliens” that she overdid herself. Reese Witherspoon 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?’” Looks like Reese Witherspoon really does have the makings of a great action hero… of course, there is no more competition lately, it seems since Arnie is off governing California and Bruce Willis is a family man these days.
