True. Very true.

I think our "takeaway" from all this might be that we admire Robert Zemeckis for doing such a great job with the special effects methods he had at this disposal in 1989, and he produced a movie we can still enjoy in 2017, despite the fact that modern film-making methods can easily do things that were very difficult back then. Very Happy

That was my thinking too, especially in view of the fact that I don't think the technology for "removing the wheels" existed in 1989.

It probably could have been done with multiple camera passes and a roto-matte, but it would have been expensive and time-consuming.

Basically nearly impossible at the time the film was done. You'd need a clean plate of the street to fill in any handmade mattes to get rid of the wheels and stuff, which would be basically impossible to get in that time, since contemporary motion control cameras were not really used for live action photography, and certainly basically impossible for those tracking shots down the street. And even if they could, trying to matte that mess without visible lines or color shifts would have been next to impossible.

If you see the actors and boards and the street all at once, they're on rigs and it's all in camera.

I think it could have been done relatively well [the hoverboard 'off the ground' effects] with front projection, this worked pretty well for the flying shots in the Chris Reeve-era Superman movies.

Front projection gives a much brighter background image as well as a wide field of vision compared to rear-projection, and in the third FUTURE movie where bluescreen-greenscreen has been used for the shots where Doc is gliding on a hoverboard carrying Mary Steenburgen, parallel to a locomotive, the results are OK but a bit obvious-looking.

Thanks for all your input in this aspect, guys: very interesting discussion.

I agree that the scene of Doc and Clara peeling off from the train was a less impressive FX than most of the ones in the Back to the Future trilogy.

That final shot with the gliding train zooming straight towards the viewer was a beauty, though, Bud!

When I watched that train wreck of a "Time Machine" remake, during the fight on the time machine, the only thing I could think of was Doc Brown comment about his time train. Marty! It's steam powered!

Well, you know what they say — different strokes for different folks.

I love the 2002 The Time Machine, even though it took me a second viewing to understand the brilliance of the concept which states, in effect, "You can not use a time machine to prevent an event which was the direct cause of the time machine's invention in the first place."

I'm not criticizing folks who didn't care for it. To each his own. Very Happy

Hiya folks, it has been pointed out that motion control was not availible for live-action shooting in time to work its' wonders for 'removing the wheels' in the hoverboard shots for FUTURE 2 released in 1989.

However!!

I have recalled at least ONE instance of where motion control technology was used commercially in 1988:

This was the Jeremy Irons film DEAD RINGERS in which he played identical twins: 'they' are seen together in the same moving shot using the same tracking used — identically — twice, then spliced together seamlessly, presumably using analog methods.

However, I will concede that perhaps the moving camera in this instance was mounted on a track [like for the Star Wars model spaceship motion control shots] which would have been much harder — if not impossible — to pull off for the hoverboard shots in FUTURE 2.

________________________________

I posted a fan-made trailer for The Last Starfighter (1984) on the thread for that movie, and the trailer had this amusing message at the beginning.






I wondered just how true the claim at the bottom was, so I made a list of 1980s science fiction films that I thought were good, just to see if that decade really did produce a significant number of “the best” sci-fi movies.

This movie is on the list I made. I know what I like about the film, but I’d like to hear the pros and cons from the rest of you folks.

So, what do you think, guys? Cool

I recently was reminded of my favorite scene, which I still think is genius. Marty is talking to his future Dad, all the while twisting at the bottle cap on his Pepsi. His future Dad grabs the bottle and uses a mounted bottle opener, then hands it back to Marty's confusion.

At the time twist-off bottle caps that looked like regular were less than ten years old. But Marty was young enough to not remember when you had to use a bottle opener. But because the bottle caps didn't look any different, he wouldn't notice the difference in the 50s, or to use a bottle opener because he had no experience with them. A genius fish-out-of-water scene.

In 1978, I was working for Barker's Department Store, and one of my duties was stocking the soft drink machines in the brake room. The machines dispensed glass bottles, which were still the norm for drink machines. Nice, until the machine breaks a bottle, and you spend 60 to 90 minutes cleaning the glass and drink out of the machine. One day I noticed something different about the bottle caps, they had a line of instructions on how to twist the cap off.

Later in the day, I'm taking my break in the break room with my coworkers, we're all talking. I take my Coke and twist off the top...And EVERYONE stops talking. I look around, confused and someone points at the bottle and asks, how did you do that!? I show them the cap, saying that it's a twist-off. We all laugh, but for a few seconds, I had everyone amazed. Laughing

David.
