Tachiguishi-Retsuden (立喰師列伝) is a 2006 Japanese animated comedy film directed by Japanese filmmaker Mamoru Oshii, who also wrote the eponymous novel on which the film was based. Both works are part of the Kerberos Saga. Live-action film and manga adaptations were produced few months later in Japan.

Superlivemation
Tachiguishi-Retsuden is a documentary-style animation film created with an innovative technique named "Superlivemation". Oshii first experimented this flat 3D technique in his 2001 live-action feature Avalon as a visual effect for explosions in Ash's game, then he developed it, the following years, in both the MiniPato short films and PlayStation Portable game. Characters have a tiny body and an oversized head which makes them look funny.
They are animated like paper dolls (ペープサート人形, papsart ningyou) and are evolving in a pictures based environment in the likes of the JibJab Brothers' (Gregg and Evan Spiridellis) musical comedy cartoons, e.g. 2・0・5 Year In Review, although Mamoru Oshii stated his own work was a "serious comedy".
The Superlivemation consists of digitally processing then animating, paper puppet theater-style characters and locations based on real photographs.
