- "Shark still looks fake."
- —Marty McFly
The Holomax Theater was a movie theater building in downtown Hill Valley surrounding the Courthouse Mall. It showed holofilms, where holographic technology made the viewer feel as if they were in the movie.
When the Holomax Theater played Jaws 19 in October 2015, the exterior of the building would create a giant hologram of a shark from the movie and 'swallow' unsuspecting bystanders — as it did with Marty McFly, who thought the shark still looked fake. The Holomax Theater took on the former site of the Essex Theater.
A thumbnail of the Holomax Theater appeared in the Newsline column of the October 22, 2015 issue of USA Today, with the accompanying caption "Hill Valley Theater will close Tuesday". (As October 22, 2015 was a Thursday, this meant the theater would close on Tuesday, October 27.) However, it was never revealed exactly why the theater was closing.
On September 7, 1893, Dr. Emmett Brown traveled in the second DeLorean time machine to October 27, 2017 to find an eighth wedding anniversary gift for his wife Clara; he eventually bought a copy of Lighthouse at the End of the World by Clara's favorite author, Jules Verne, from the Blast from the Past antique/memorabilia store. While in 2017 Hill Valley, Doc passed the Holomax Theater where the movie remake of A Match Made in Space was being shown. The exterior of the building created a giant holographic image of the alien which appeared to reach down to grab Doc, during which he remembered that although the original movie hadn't been great, "the book was really something special".
- As of 2015, the holographic billboards and hologram theaters don't exist. Currently at movie theaters, people have to wear 3-D glasses in order to see 3-D movies. While some devices use stereoscopic 3-D techniques to display three-dimensional effects without the need for glasses — such as the Nintendo 3DS, which uses parallax barrier autostereoscopy — these techniques are unable to produce the holographic effects witnessed by Marty at the Holomax Theater.
- The conversion from a porn theater in 1985 back to a mainstream one is accurate as most porn theaters have long since closed, the internet offering such diversions with much greater (perceived) privacy. Really, they were fading fast in the 1980s due to the advent of VHS.
