The Hollywood premiere of children's movie Horton Hears A Who! was turned into a protest on Saturday when a group of pro-life activists crashed the event to campaign against abortion.

Campaigners were overheard shouting the message of the film, an adaptation of the 1954 Dr. Seuss story, which is based on the motto: "After all, a person is a person, no matter how small."

After chanting, the group put red tape labeled with the word "life" over their mouths and proceeded to parade around the Mann Village Theater where the film's stars Steve Carell and Jim Carrey were in attendance, reports TMZ.com.
