This study addressed the questions of whether or not the IMAX/OMNIMAX film "Tropical Rainforest" contributes to a positive attitude towards, and and increase in knowledge about, the tropical rain forests of the world. Results indicate that there are statistically significant increases in knowledge gained as well as an increase in positive attitudes towards the tropical rain forests. All three specific audiences (grades 1-6; grades 7-12; adult general) tended to increase overall.
