The second movie in the set includes seven deleted scenes that are again available with or without commentary by Bob Gale. A couple of them are new, but most are extensions of existing scene such as an extended version of the moment where Jennifer faints, which features some incomplete effects work. The outtakes reel on the disc only runs for 46 seconds.

With the focus on Marty, Doc, and the Doc's love interest (Mary Steenburgen), the film returned to the smaller nature that the first movie had, and is less of an effects romp than the second. It's also pretty well contained. While the second movie does set up the events in this installment, everything the viewer needs to know is recapped early in the movie. When Marty asks what the DeLorean runs on instead of gasoline, Doc tells him it needs plutonium, explaining that a nuclear reaction is necessary to generate 1.21 gigawatts to power the flux capacitor. Marty is alarmed, asking where the Doc could possibly have gotten such a substance and Doc tells him that he hired a couple of Libyan terrorists to steal it for him with the promise of building them a bomb. Doc, however, cheated them, delivering a fake bomb. Pepsi produced a limited run of the "Pepsi Perfect" soft drink, including the unique bottles, which sold out before October 21, 2015.

On the 30th anniversary of his arrest, on October 21, 2045, he uploaded a virus that was supposed to flash the word "butthead" on everything. However, it short-circuited the Mr. Fusion network, causing nuclear explosions in 100 million homes worldwide.Lawson, Sean (May 9, 2023).

Faithfully recreated details from the film trilogy include wheels that fold down for flight mode, the iconic light-up flux capacitor, printed dashboard dates, opening gull-wing doors and hood and many more Easter eggs including Marty’s hoverboard and swappable license plates. The set even comes with a banana and tin can, to power the Mr. Fusion device as seen on the vehicle at the end of the first movie. Marty suddenly sees a way to get George to win Lorraine's heart. Marty approaches George while George is doing his parents' laundry, and tells him to find him with Lorraine in Doc's car in the school parking lot at a certain time, where Marty plans to appear to "take advantage" of her.

As if on cue, exactly one minute later, the DeLorean materializes where it disappeared, still traveling at the same speed as it was before, and screeches to a stop, now iced over. As Doc opens the door, Einstein is revealed to be alive and well, with his watch now one minute behind Doc's. Doc explains that Einstein likely believes that the trip was instantaneous. Doc shows Marty a device in the cabin called the "flux capacitor" which makes time travel possible. Doc explains that, after an accident in his bathroom in 1955 where he hit his head, he had a vision of the flux capacitor. Though it took 30 years of research and most of his family's fortune to develop it, the project is a success and Doc plans to travel through time. As he talks to Marty, Doc absently sets the vehicle's destination time to that date.
