From the Hollywood Reporter comes word of some Classical connections in an upcoming movie called Snow White and the Huntsman … inter alia:
In the script, the dwarfs are named after Roman emperors with McShane playing the group’s leader, Caesar, Jones as a timid dwarf named Claudius and Izzard playing Tiberius, described as the biggest and burliest of the crew. Hoskins will play Constantine, a blind dwarf, Graham an angry-looking dwarf named Nero.
Winstone is playing Trajan, the twin brother of Hadrian (Marsan).
Not sure why they’re named after Roman emperors … did they have names in Grimm?

No names in Grimm. But dramatization requires that they be individualized, and Roman emperors are as convenient a device as any, and one that is nicely safe against Disney’s legendarily formidable legal staff.
