Having just exited the train that toured the crystal planet Midnight, The Doctor had embraced his companion Donna Noble, knowing that he almost died on that train. He decided it was time to unwind for a while. The Doctor said to Donna: "How about a little relax trip? A time to unwind." Donna hastily agreed but asked where they would go. The Doctor quickly responded: "how about we watch a World War II propaganda film get made?" Donna replied: "didn't Chaplin do one of those?" The Doctor remarked: "well, yes but I want to unwind by laughing, not sleeping. I mean a comedy team." "Who?" exclaimed Donna. The Doctor assured "you'll see! Now, Allons-y!" as the TARDIS was set to 1940 in Columbia Studios, Los Angeles.
