Gilliam finished editing the film by November 2008, and then work began on creating 647 computer generated imagery effects shots. As usual with his films, Gilliam found inspiration in particular painters for each CGI-generated scene inside the titular "Imaginarium". According to "Designing the Imaginarium" published by CBSnews.com, the scene with Doctor Parnassus's attempted suicide related to the style of Odd Nerdrum, the "Ladder World" with Jude Law featuring "rolling hills with simple trees" was inspired by the art of Grant Wood, the kitsch landscape from the beginning of the sequence with Colin Farrell took inspiration from Maxfield Parrish, and Jose Maria Sert's mural of the Crucifixion in Rockefeller Center inspired the scene including the final minutes of Farrell's appearance in the film.
