The Hedge of Thorns (original title: Tornehekken) is a 13-minute animated short film written, directed, photographed and animated by Anita Killi, based on the picture book "Florian and Malene" (1993) by Elizbieta. Released in 2001, it uses Killi's distinctive cut-out and multiplane technique — the lyric-poetic style found throughout her work — to tell a story of war seen through a child's eyes. Editing is by Pål Gengenbach, with an original score by Hege Rimestad.

The film became the most internationally awarded Norwegian film of 2002 (Aftenposten), collecting more than 20 awards and nominations between 2001 and 2003 — among them a Crystal Bear special mention at the Berlin International Film Festival, the UNICEF Award at the Annecy International Animation Film Festival, the Liv Ullmann Peace Prize at the Chicago International Children's Film Festival, and Best Children's Film at Oberhausen.

The Hedge of Thorns was produced by Anita Killi at Trollfilm AS, the animation studio she founded in 1995 in Dovre, Norway — since grown from an old cow barn into a state-of-the-art animation facility. Like much of Trollfilm's work, the film approaches a difficult subject gently, through poetry and image rather than explanation. More than two decades after its premiere, it remains in active use in schools and therapy rooms, helping children process the impact of war and conflict on their lives and friendships.
