Well... That Announcer beat me to it, but... Here's my Back To The Future cast lineup. Dr. Emmett L. Brown: Doc (from FR). Marty McFly: Scooter. George McFly: Bert. Lorainne McFly: Annie Sue. Marty's Brother, was it Dave?: Grover Monster. Marty's Sister: Mokey Fraggle. Jenny, Marty's Girlfriend: Prairie Dawn. Einstein, Doc's Dog: Sprocket. Biff Tannen: Link Hogthrob. Biff's Henchmen: Andy and Randy Pigs. Principal Strictland: Sam the Eagle. 1955 Timeline. Marty, still Scooter. Young George: Younger version of Bert. Young Lorainne: Younger version of Annie Sue. Young Biff: Younger version or perhaps just the same ol' Link Hogthrob. The Band: The Electric Mayhem. Clifford would be there in the band too, as the character who was the cousin of Chuck Berry... Remember? The guy calls Chuck to tell him about the song Marty's performing, Johnny B. Good, which was recorded by Chuck and that's why Marty knows it and thus how Chuck comes to record it. Young Emmett Brown: Perhaps just Doc again. Copernicus, Doc's dog: Sprocket or maybe Rowlf The Dog. Just LMK when the next one after Hitchhiker's Guide's been posted.
