Happy Days: Then, Now, And Fun Facts
Happy Days Started As A Different Show With Some Of The Same Characters

Happy Days started as a different show in 1971 and it was called New Family In Town. That show was also produced by Garry Marshall for ABC. The pilot even had some of the same characters (Richie, Howard, Marion, and Potsie) and some of the same actors (Ron Howard, Marion Ross, and Anson Williams). Harold Gould played Mr. Cunningham in that show.
