Like the original series, "The New Adventures of Gilligan" contained an adult laugh track, which was common practice with most Saturday-morning cartoons of the era. One unique feature of "Gilligan" was the fact that it was produced and animated in the United States, where most shows at that time were animated overseas in order to cut production costs. However, Filmation's dedication to having its shows produced locally did not help the production values, as many felt the animation of "Gilligan" was of poor quality. As the series did not secure the rights to "The Ballad of Gilligan's Isle", a spoken-word poem with lyrics and backing music vaguely reminiscent of the theme (but distinct enough to avoid copyright issues) was substituted as the opening introduction. All of the voice actors except for Bob Denver read portions of the poem.
