Per the title, Grauman's Chinese Theater is a movie theater located at 6925 Hollywood Boulevard in Hollywood along the historic Hollywood Walk of Fame. The Chinese Theater was commissioned following the success of the nearby Grauman's Egyptian Theater which opened in 1922. Built over 18 months, beginning in January 1926 by a partnership headed by Sid Grauman, the theater opened May 18, 1927 with the premiere of Cecil B. DeMille's film The King of Kings (1927) and hosted three Academy Awards ceremonies. In the theater's forecourt are the signatures, footprints, and hand prints of popular motion picture personalities from the 1920s to the present day.
This is the first episode to be written by new writers Bob Schiller and Bob Weiskopf, who joined the cast in season 5. As a season premiere, this episode wasn't all that well-received, and critics disliked the overall script, saying that the episode was only good because of Lucille Ball's many ad-libs. What the critics didn't know is that there weren't any ad-libs at all, and that all of the clever gags were SO well-written by the two new Bobs that the dialogue seemed effortless and unscripted.
While in Hollywood making the MGM musical about Don Juan, the movie got shelved, but Ricky was put into another movie. It is never said what the final movie he made was called or what it was about.
In real life, if Lucy had dropped the cement slab on her fingers, the bones in her hands would have been smashed and broken to pieces. But all Lucy suffered from was sore hands, no injury. Similarly, The Lucy Book author Geoffrey Mark Fidelman notes that, if Lucy's cement-covered foot had dangled off her couch in the Mertzes' suite the way it did, her foot would have come off. The "cement" was really mostly Styrofoam. Some hard material was added that Desi could chip away at with the hammer.
Starting with this episode, Irma Kusely takes over for Bert French as Lucy's hairstylist on the show. Previously, Kusely had only done Lucy's hair while she was pregnant, back in season 2. She will do Lucy's hair for years to come.
