Jelly T (Danish: Gummi T), also released as Ivan the Incredible,[1] is a 2012 Danish 3D superhero computer-animated comedy film directed by Michael Hegner from a screenplay by Michael W. Horsten, based on the 1975 children's book Gummi-Tarzan by Ole Lund Kirkegaard.

[6] Ivan Olsen is constantly bullied at school, mostly by his father who is angry at his inabilities of being both smart and strong enough to protect himself.

Lotte, a cute girl wishes to be a friend of his but Ivan unwillingly disagrees believing he can't do anything at all.

However, when Walt Disney Pictures released their animated film Tarzan in 1999 they secured the exclusive rights to the title.

After publishers of Ole Lund Kierkegaard's book were threatened with legal action, they reached an agreement with Disney that the original book may be freely republished as Gummi-Tarzan, but that in all other media the title must be Gummi T (English: Rubber T).
