Passage: The film was announced via Variety in December 2012. Bobin was first approached about the project while doing post-production work on Disney's Muppets Most Wanted. Of being asked, Bobin has said that "I just couldn't pass it up", as he has a passion for the works of Lewis Carroll as well as history in general. In July 2013, it was announced that Johnny Depp would return as the Hatter, with Mia Wasikowska's return confirmed the following November. In January 2014 Sacha Baron Cohen joined the cast to play Time. In May 2014, Rhys Ifans joined the cast to play Zanik Hightopp, the Mad Hatter's father. In developing the character of "Time", Bobin sought to avoid creating a "straight-up bad guy", noting that it would be "a bit dull", and also that the role in that universe already existed in the form of The Red Queen. Instead, Bobin sought to make Time a "Twit", further explaining that "There's no one better at playing the confident idiot trope than Sacha Baron Cohen", and adding that "it was very much with Sacha in mind".Principal photography began on August 4, 2014, at Shepperton Studios. In August 2014, filming took place in Gloucester Docks, which included the use of at least four historic ships: Kathleen and May, Irene, Excelsior, and the Earl of Pembroke, the last of which was renamed The Wonder for filming. Principal photography ended on October 31, 2014.
