Continuity mistake: When Nino collapses (camera positioned behind Jigen's head) you can see a blood streak on his right arm as well as the left arm. In the rest of the scene he has blood only on the left arm. Moreover, when Jigen picks him up the puddle of blood on the floor has a different shape compared to what we see when he leaves doctor Livia to her medical duties. (00:12:20)
Continuity mistake: The quantity of super-steroid in Fukegao (the mad scientist) 's test tube changes continuously between shots. (00:11:00)
