When Back to the Future was released in 1985, there was no intent for any more films. The ending was not a teaser for a sequel. However, the movie made a lot of money and was very popular, ensuring the studio wanted more movies. It would get them in 1989 and 1990 with Back to the Future, Parts II and III. The two films were shot back to back.
That's about a half decade delay between the first film and it's sequels. In the intervening time, careers and film culture had continued. What if the sequels had been made earlier? Assuming a year to two years to make a film, perhaps seeing release in 1986 or 1987?
