Actress Reese Witherspoon recently took her children to view her upcoming 3D computer animated movie Aliens vs. Monsters. When asked what they thought the message of the movie was, nine-year-old Ava responded that it was about living up to your true potential. Taking a more practical view, Deacon, age 5, said the message was that it was important to kill octopus aliens when they invade your planet. In the movie, Witherspoon is the voice of Susan, a woman who grows to 42 ft. 11 inches tall and helps save the planet from aliens.

Also gracing the April cover of Elle magazine, Witherspoon opens up in a feature about many things, including her “humiliating and isolating” divorce from Actor Ryan Phillippe, the father of Ava and Deacon.

Asked about her rumored “Type A” personality, she told the magazine, “I don’t think I’m a control freak … I’ve been portrayed as a very, like, closed-off or uptight person. I’m very open.”

Aliens vs. Monsters is scheduled for release in the U.S. on March 27, 2009, and for U.K. release on April 3. The movie features voices of Paul Rudd, Hugh Laurie, Seth Rogen, Will Arnett, Rainn Wilson, Stephen Colbert, and Kiefer Sutherland in addition to Witherspoon.
