This was Jackson Bostwick's final episode as Captain Marvel. Bostwick had not shown up for a day's shooting, and the producers, Lou Scheimer and Norm Prescott, accused him of holding out for a higher salary. Bostwick explained that he had sustained an injury during the previous day's filming and had gone to seek medical treatment - he even had the nurse at the doctor's office talk to Scheimer and Prescott on the phone, but they didn't believe him.
In an interview, he stated, "I was at the doctor's office having my face and eye examined for an injury that I incurred doing a stunt on the previous day (during the filming of a flying takeoff sequence where the stunt boxes hadn't been reset properly)." He successfully litigated against Filmation Associates, who were forced to pay him for the remainder of his contract (the rest of the second season and the entire third season) including residuals.
