Theatrical Release Information:
Our Lips Are Sealed

In this comic adventure story, Maddy (Mary-Kate Olsen) and Abby (Ashley Olsen) are twin sisters (sounds reasonable) who accidentally witness a felony and soon find they're being chased by hoodlums who want to make sure they keep quiet about what they've seen. Hoping to keep the girls under wraps so they can testify against the crooks, Maddy and Abby are placed into the FBI Witness Protection Program; however, the girls have a tragic inability to keep a secret, and before long the FBI decides the best approach is to simply ship the twins out of the country until they can testify. Maddy and Abby are sent to sunny Sydney, Australia, where they find sun, fun, and danger when the gangsters discover them down under. Our Lips Are Sealed was released direct-to-video on November 21, 2000. ~ Mark Deming, All Movie Guide
