George Reeves wasn’t credited
George Reeves, who was already well-known for his role as Superman in the film industry, made an uncredited guest appearance on the show. Many younger viewers saw him as a real superhero rather than just an actor playing a fictional character.
Lucille Ball decided to keep his name concealed during his appearance to preserve the illusion for these young viewers and maintain their belief that Superman was a genuine figure.
Vivian’s husband was jealous of the cast relationships
It turns out that Lucy Ball wasn’t the only member of the cast dealing with a difficult marriage. Vivian Vance, who played Ethel Mertz, experienced abusive behavior from her husband, Phillip Ober, which made her feel unappreciated. Seeking inner peace, Vivian turned to therapy for support.
As Lucille Ball and Vivian developed a close and inseparable friendship on set, this understandably upset Phillip, leading him to try to drive a wedge between the two women. At one point, he never attempted to convince Vivian that rumors about a romantic relationship between them were true!
