The main-on-end credits were animated in stop-motion, unlike the rest of the movie's CGI. The sequence was created by the studio Alma Mater with Stoopid Buddy Stoodios and took almost a year to produce.
Except for the Warner Bros. Pictures and Village Roadshow Pictures logos and even the debut of the Warner Animation Group logo (all presented in LEGO), there are no opening credits, not even the film's title, which doesn't appear until the end of the main-on-end credits.
According to the DVD commentary, Will Forte was billed as "Orville Forte" due to a typo. Forte's actual first name (his full name is Orville Willis Forte IV) rather than his professional name was listed on a form used when compiling the end credits. When informed of the mistake, Forte asked the producers to leave the "incorrect" billing as it was. Thus, the voice of "Abraham Lincoln" remained credited to "Orville Forte."
