Brainstorm by Douglas Trumbull (1983)

About

Unit 23 operates as a critical practice to establish and evolve the agendas, methods, attitudes and directions its graduates will take beyond the institution. We approach the subject and discipline of architectural production as a broad and curious field that oscillates between meaning and means, representation and realisation, experience and expertise. We investigate and experiment within the operations, protocols, roles, deceptions and tales of making experimental architecture. Students are expected to take possession of their work as critical research in developing their knowledge, skill and ideas.

Everyone knows this was Natalie Wood's last film, and that some of her scenes were filmed after her death with a stand-in you only see from behind. Director Dondald Trumball, best known for his special effects work in Blade Runner, Close Enounters, a Star Trek, chose this time to build his story on plot and character development, a good choice given the enormous talent he had to work with.
Trumball's battle with studio execs to finish the film after Wood's death, rather than claim the insurance proceeds and call the film off, ended his career in Hollywood, but assured that this gem would not be lost. It is somewhat ironic that Natalie's swan song should be a sci-fi movie, since she was hardly known for work in the genre, but she brings a grace and charm, as well as depth and beauty, to the genre that is usually lacking.

Most sci-fi films based on technology don't age well, and there are times where this is no exception. The idea of recording on tape, let alone making tape loops, must seem like wax cylinder recordings to today's MP3 generation. The tapes themselves were props borrowed from a film being shot nearby, and that film was itself a dismal failure. But the concept is timeless, and so well done that, all in all, the film still works as well as it did in 1983.
