This short is a promo for the 1984 film "2010", and it is occasionally shown on TCM.
This short provides a behind the scenes look at the making of the film, and is a mixture of talking head shots, footage of the development and construction of sets and visual effects, footage of action and filming on the set, and a few clips from the finished film. After science fiction author Arthur C. Clarke makes some opening comments, an uncredited narrator introduces us to a series of cast and crew who each discuss various aspects of the making of the film. These include writer/director Peter Hyams, visual futurist Syd Mead, production designer Albert Brenner, visual effects supervisor Richard Edlund, model shop supervisor Mark Stetson, makeup supervisor Michael Westmore, and actors Keir Dullea, Roy Scheider, John Lithgow, Bob Balaban, and actress Helen Mirren.
Some of the topics discussed are Clarke's and Hyams working together via computer since they were half a world apart, the design philosophy of the sets, makeup for Keir Dullea's elderly character, the difficult tasks of creating the illusions of spacewalking and weightlessness, the American/Russian "detente" theme, differences between this film and 2001, and the ambiguous meaning of the monolith.
Some of the stuff here wasn't that enjoyable, but the short does have enough to be moderately interesting. Things like... while the look of 2001 was supposed to be beautiful and visionary because it was supposed to be about the distant future, the look of 2010 was intended to be functional and realistic so that the audience would think "that can actually happen in the near future". It was also interesting to find out that they had to completely recreate the spaceship Discovery design from watching the film 2001 because Stanley Kubrick had destroyed the models and all detailed design info fearing that it would be copied and used by others.
Overall... I found the discussion of the technical crew interesting but most of the stuff the actors had to say was forgettable.
