- Nero remarks on the idea of creating an experience in order to gain inspiration, and complains that for his "conflagration", he has not yet seen a burning city. Petronius replies; "A burning city? That would be carrying art for art's sake too far". "Art for art's sake" is of course the motto of the studio that made the film, MGM.
- Filmed at the new Cincecitta Studio in Rome, a long delayed production complex originally conceived by Benito Mussolini and Hal Roach under their proposed R.A.M. ("Roach and Mussolini") Corporation, which was ultimately aborted. This fascist business alliance horrified 1930s' studio moguls and ultimately led to Roach defecting from his MGM distribution deal to United Artists in 1937. This new studio complex offered massive sets and cheap Italian labor. It would be later utilized by many producers, including Federico Fellini.
- In An Audience with Peter Ustinov (1988) (TV), Ustinov recalled that he had been attached to the role of Nero for over a year before filming began. During this time he received a memo from the producers, informing him that they still wanted him for the part, but were concerned that he was too young. Ustinov replied that Nero died when he was 31; if they waited much longer, he would be too old for the part. He then received a reply, which he said he had kept and treasured. The reply stated: "Historical research has proved you correct."
- John Huston was originally supposed to direct this film, but walked out following arguments about the script. He was replaced by Mervyn LeRoy.

- Sophia Loren has an unbilled bit part as a slave girl. While not her first film, it was her first American film, although it was shot in Italy.
- Robert Taylor's hairy chest had to be shaved for his part because the studio thought a man's hairy chest was too "sexy" for a biblical film.
- Re-released by MGM in 1964 to pad its 40th-anniversary schedule.
- The film represented a hollow victory for MGM studio chief Louis B. Mayer, since it turned out to be his final big-budget production. Produced for $7 million, it was MGM's largest grosser since Gone with the Wind (1939), but Mayer was forced out of his job prior to its release.
