- "After facing the tension of doing three lung operations in a row, I like to relax by lighting up a Sir Walter Randolph. I know that the fine tobacco taste will soothe my nerves and improve my circulation."
- —Doctor in commercial
- Marty: "Cigarette smoking causes lung cancer. How can he do lung operations and then puff a cigarette? It's crazy!"
- Sam Baines: "Well, they ain't proved anything yet. Don't see why a doctor can't advertise cigarettes if he wants to."
- Marty: "Because it's immoral."
- Sam Baines: "Don't be silly."
Sir Walter Randolph was a brand of cigarettes. In 1955, a commercial for the brand showed a doctor endorsing their product after performing three consecutive lung operations.
Marty McFly had never seen a cigarette commercial on television, and was amazed to see a lung surgeon endorsing cigarettes. Marty and Sam, being from eras 30 years apart, had different viewpoints about the health risks of tobacco.
Behind the scenes
- This scene appears in the Part I novelization, but not in the final version of the film. Although the novelization was based on the script, it is not known whether this was in footage cut from the scene of dinner with the Baines family, or if it was ever filmed at all.
- The commercial part of the scene was announced as a deleted scene for the first DVD release, but was later removed. However the scene was found to be left on the disc between the "Pinch Me" and "Doc's Personal Belongings" deleted scenes. The doctor in the commercial is played by John McCook. Later releases removed the scene.
- Cigarette advertising on television was banned after January 1971, with the final ads shown during Super Bowl V. Marty, who would have been two years old at that time, probably did not remember having seen a cigarette commercial before.
- "Sir Walter Randolph" is likely a parody of Sir Walter Raleigh, the English explorer who popularized tobacco, and whose name is used for a brand of pipe tobacco.
