Warner Home Video announced Monday that it plans to re-release the documentary March of the Penguins on video-on-demand with a special pop-up window feature that will enable viewers to obtain additional text information about what they are watching in the film. The company said that it will be the first time any movie has been released with pop-up technology employed throughout, not just in the bonus material.
