Core 77 have picked up a wonderful video looking at the design of spacesuits for movies. These are From Ridley Scott's latest Alien film.
Even though they're not going into space these suits have an amazing amount of tech in them.
built in ventilation fans
built in lights, displays etc
control circuitry which allows the director to adjust the suits' lights and other visible components all together.
Even the soles of the boots are imprinted with the logo of the Wayland Yutani Corporation logo, the best name for a company ever. Well second best.
