This is the first I'm hearing about Back To The Future Parts II & III being filmed at the same time in addition to Season 7 of Family Ties all filming concurrently. I knew that Back To The Future Part I was being filimed at the same time that Season 3 of Family Ties was being fimed.

I don't know how reliable it is, but I guess anything is possible. If both Parts II and III of BTTF and Family Ties Season 7 were all filmed at the same time that must have been really hard to accoplish. I wouldn't think there would be enough time for three projects like that all at once.

Michael J. Fox says that shooting "Back to the Future" parts 2 and 3 simultaneously in 1988—an unprecedented feat at the time—was brutal. At the same time, he was finishing up his final season on "Family Ties."

"I got married at the beginning, just before we started shooting. My son was born in the middle of it, and my father passed away in the middle of it," recalls Mr. Fox. "It was a big chunk of my life."

Executives decided to make the "Future" sequel into two movies after they saw the screenplay for part 2—which was so long and complex it would have resulted in a film that was more than three hours long and prohibitively expensive to produce, says Tom Pollock, then head of Universal Studios. Because a two-part sequel was unusual, executives worried that audiences would see each film as only half a movie—and skip them both. "What we said was that each movie was complete in and of itself," says Mr. Pollock.

I can recall this well when they were filming BTTF 2 & 3 I went to Universal Studio and they were in the middle of filming a scene for part two they had sets from both movies and the tour guy commented on how busy Michael J Fox was.

So BTTF Parts II & III weren't filmed at the same time? So BTTF Part 1 & II were filmed at the same time plus Season 3 of FT in 1985? I don't think that they filmed BTTF Part II in 1985. I suppose that's possible though.

Parts 2 and 3 were filmed at the same time. I remember reading about it at the time. Plus I was a big MJF fan so I followed him quite alot back then.

That can't be true. They couldn't have had part 2 in advance while shooting part 1. You're probably remembering things wrong. I even remember Bob Zemeckis clearly stating that they never designed the first movie for a sequel.

Yea for one thing, nobody knew how popular it was going to be while they were filming it. I think he probably meant Parts 2 and 3.

Yeah clearly I meant 2 and 3 just a typo.
Some are so eager to jump on others yikes!
