Season two, episode four, "Photo Finish". As a child, Robert Englund, who was anxious to watch a Western, wound up watching The Bad Seed (1956) due to a mix-up at the television station. He's been quoted as saying, "For years I was frightened of girls with pigtails." In this episode, he got to face-off with the now grown-up girl that terrified him, Patty McCormack.

This is also known as "FreddySomething", which is a take on the television series, Thirtysomething (1987).

Season one, episode two, "It's a Miserable Life", in the hospital, there's a poster in view that reads "Mom and Dad, I use drugs!" This is the first time this poster was seen in the series, but it became a regular staple of the set dressing in subsequent episodes.

There are several Star Trek references: The psychologist is named Dr. Picard, like Captain Picard from Star Trek: The Next Generation (1987). When Johnny disintegrates, his last words are "Beam me up, Scotty". During Dr. Picard's daydream, when he's infected, he shouts "Captain, the dilithium crystals are gone!". Tim Russ, who played Dr. Picard, went on to star in Star Trek: Voyager (1995) as Commander Tuvok.

The house, in which John lives, is the same house, in which the Blocker family lived, earlier in the season.

Season two, episode seventeen, "Interior Loft Later", is the only sequel episode that was filmed and aired consecutively with the episode it followed.

Rick mentions that the Beefy Boy is closing early, and the owner never comes in since "the shooting". This is a reference to season one, episode two, "It's a Miserable Life", in which the employee (who is the owner's son) is shot at the drive-thru during his nightmare.

Season one, episode one, "No More Mr. Nice Guy". There's more than a few inconsistencies between this episode and the established story from the films. In A Nightmare on Elm Street (1984), it was stated that Freddy was released because "somebody forgot to sign the search warrant in the right place." Here he was released, because the arresting officer didn't read him his Miranda rights. Lieutenant Blocker is never mentioned in the films, and the Thompsons from the first movie, who were part of the mob, aren't mentioned here. Marge Thompson said of Krueger's death that the parents left a trail of gasoline through the boiler room and out the door, lit a match and watched it burn. Here, however, Lieutenant Blocker douses Krueger himself with gas and lights the match. In Freddy's Dead: The Final Nightmare (1991), the mob is seen throwing a Molotov cocktail into Krueger's lair, which is also inconsistent with his death here. In that film, he's merely surrounded by flames when the dream demons arrive to offer him immortality, he's not actually on fire. In the first film, Marge Thompson revealed that she took Freddy's glove as a souvenir after they murdered him. No reference is made to anyone doing this here. In this episode, it's officer Gene Stratton who hides Krueger's remains, but in A Nightmare on Elm Street 3: Dream Warriors (1987), Donald Thompson was revealed to be the only one who knew where Krueger's corpse was hidden. There's been some speculation as to whether or not Stratton was supposed to be Thompson, but Stratton wasn't present when Krueger was murdered, as Thompson was alluded to have been. Additionally, the time period, in which No More Mr. Nice Guy takes place, throws the rest of the Elm Street timeline completely askew. In A Nightmare on Elm Street (1984), Nancy watched The Evil Dead (1981) on her television, and has a poster of the band The Police on her wall, which establishes the film taking place in 1983 or 1984. Since Nancy and her friends were unaware of Freddy (and a deleted scene reveals the kids who were being terrorized in the first film each had siblings who were murdered by Krueger), Freddy's death would have been in the late '60s or early '70s. No More Mr. Nice Guy is supposed to be a prequel to the first film, however, the look is very late '80s and (in addition to the vehicles) Lieutenant Blocker winds up wearing a Walkman style of headphones that weren't around in the '60s and '70s. The timeline is thrown into further disarray by the sequel to this episode, Sister's Keeper, where a poster for Madonna's "True Blue" adorns the wall of the Blocker girls' bedroom. "True Blue" was released in 1986, five years after The Evil Dead (1981). That sets the events of these episodes after the first film.
