The film imitates the appearance of films from Classical Hollywood studio-era. Most of the scenes were shot on soundstages and on Universal Studios' backlot, and were then edited with archival Russian footage and archived film from Corbis. Although the finished film is in black and white, it was shot in color because this allowed the use of faster film than available black-and-white film stocks, and afforded the ability to use 'green screen' techniques. The color was then reduced in post-production through the use of a digital intermediate to a grainier black and white, in order to blend with the carefully restored archival material.
