Thrill Kill - S5-E1
Factual error: When Dylan gets out of jail, a palm tree can be seen in the background behind him. This reveals that the scene was filmed in Los Angeles, not Philadelphia.
Factual error: The opening scene is identified as taking place in 1980, yet the characters are singing along to "No Surrender" which wasn't released until 1984.
Factual error: Look at the area by the door when we see Margot and Spencer in the hotel room in 1989. The light switch is a flat "Decora" switch, and above the door handle is a black box that houses electronics for a "card key" system. The light switch was not introduced until the 1990s, and while the card key system was introduced in 1985, only very expensive hotels afforded the conversion costs - and the hotel they're at isn't exactly the Hilton.
Factual error: They show the side of a 1965 Philadelphia Police car. The gold shield on the door was not used until 1968.
Creatures of the Night - S2-E21
Factual error: Mike and Kelly are at the theater watching "Rocky Horror Picture Show" in 1977, talking during the song "Sweet Transvestite." After the line "satanic mechanic" and the audience callback "S and M.", which is only about two thirds of the way into the song, the music suddenly crescendos and ends, to be replaced by the song "Touch-a Toucha-a Touch Me," which occurs several scenes further into the movie.
Factual error: They show a 1965 flashback of a blue Philadelphia Police car. The Philadelphia police didn't go to the blue cars until 1973 when Mayor Frank Rizzo saw that New York went to the blue cars and liked the color. Before that the cars were red.
Factual error: When they are flashing back on "Bobby" in 1948 the actor has 2 piercings in his left ear. Men wouldn't have pierced ears in 1948.
Factual error: When Rush and Miller pull up to the vacant lot, the Los Angeles skyline is visible in the background. The series is set in Philadelphia. (00:21:54)
Factual error: In a flashback, Danny is depicted as listening to the Dean Martin song "You're Nobody till Somebody Loves You" (indicated by the change in volume when he opens the door for his parents) which wasn't released until November 1964, two months after Danny's portrayed death in September 1964.
Factual error: As Dr. Bowen is about to depart Mrs. Lee's shop, we can see a parked car outside the window that is too recent for 1984. (00:34:34)
Glory Days - S6-E1
Factual error: The episode opens in a locker room with the players singing "Taking Care of Business". However, it is supposed to be October 1973 and that song was released in December 1973.
Factual error: In the flashback where the Hathaways realise their son is missing, the vehicles parked on the street and driveways are too modern for 1987.
Chosen answer: According to IMDb.com, it is Carly Simon.
