While never outright stated, it's implied that Marlene was a cis woman (i.e. born a woman). Played by Michael J. Fox as a way to show that both his kids look just like him. It was likely meant to be a humorous sight gag with no social commentary behind it.

Back to the Future, Part II is the second movie in the Back to the Future trilogy, all of which are based on screenplays written by American film-makers Robert Zemeckis and Bob Gale. It follows Regreso al futuro (1985) (1985) and was followed by Regreso al futuro: Parte III (1990) (1990).

Theory 1: At first, this appears to contradict Back To The Future where Doc Brown demonstrates the time traveling capabilities of the DeLorean to Marty by sending Einstein 1 minute in the future, and when Einstein arrives, there is only one Einstein and not two. However, at no time ever does Einstein return back one minute to the past. He continues living on one minute in the future. We know that 1985 Jennifer and Marty return back to 1985, so their 2015 selves are most likely a continuation of themselves after returning back to 1985. Since Doc has every intention of returning Marty and Jennifer to 1985, there is no reason they should not exist in 2015.

Theory 2: Doc travels to 2015 alone after Marty makes his return to 1985. With the future not being set in stone, the future was pretty much simulated. Although it is only hours after Marty's adventure, the future senses Marty's presence. If Doc traveled to the future with Marty and Jennifer the first time, then there would be nobody living out their lives in 1985.

Depends on how detailed and varied the statistics are. We only know that it has the scores of various games and the winners of some horse races. With small enough font, the almanac could accomplish this—or by using a cross table, which could fit a whole season of results on half a page. Old Biff tells young Biff, "All you have to do is bet on the winner, and you'll never lose." This line seems to indicate that only winners across different sports are recorded in the book. It'd be pretty thin then, even for 50 years of statistics of "football, baseball, horse races, boxing."

There are two possible answers as to his whereabouts: (1) He's dead or (2) he's alive whereby we just don't see him (as he off living elsewhere or elsewhen). As for Doc's age, he was born in 1920, as implied by him being 35 years old in 1955, and thus 65 in 1985. However, there are some nuances to his theoretical age progression...

When in 2015, the 1985 Doc does state he went to a "rejuvenation clinic" and "added a good 30 to 40 years to his life." Let's just say it was 40 years "added" to his life. Depending on how you use the word "rejuvenation" (e.g. to make young again or restore to youthful vigor) and if the clinic's methods are very effective, this would now make Doc "younger" by 40 years than he really would naturally be, thus 65 years old with the vigor of 25-year-old (younger than the 2015 Marty). If he would never visit a rejuvenation clinic again yet also not do anything to accelerate his senescence, then in span of time that separates 1985 and 2015 from one another, he would become 95 years old with the vigor of at least a 55-year-old, which reduces the odds of him having died of an age-related illness. The 1985 Doc still does look 65 even having after been treated with at rejuvenation clinic which is not the equivalent of a plastic surgeon. (Which is why the subtle joke about when Doc peels off the "age makeup" and asks Marty what he thinks, Marty is clearly less than impressed as Doc pretty much looks exactly the same.)

The itv copy is missing 53.60 seconds due to 16 cuts and features 3 segments with muted/changed audio to remove some cursing. There is additional time difference due to a longer black screen at the beginning of the DVD and marginal cuts before each commercial break in the itv copy (mostly under 1 second).

After Back to the Future 2 came out in 1989, there were rumors claiming that hoverboards were real and that the Mattel company and Robert Zemeckis were hiding the hoverboard. But Zemeckis assured them they weren't real and were just special effects. There are hoverboards out there, such as the air cushion hoverboard, Zipline hoverboard, and Maglev hoverboard, or the Self Balancing hoverboard on two wheels. As for the hoverboard or flying cars as depicted in the movie, however, they do not exist, and the year 2015 has come and gone.
