This episode was originally supposed to air as the season finale for the fifth season but was not completed in time.
The series regulars appear as the residents of Cicely in this time period (a few of them the same characters they played in the 1909 piece "Cicely").
The characters are:
Joel: Mikhail, Lenin's Doctor
Maurice: Mace Mobrey
Ed: Emery Whirlwind
On the original broadcast of this episode the teaser was cut off in the Chicago viewing area, due to a local airline disaster.
