[Mild spoilers] During the production of Gravity, Jonas Cuaron (co-writer of the screenplay and Alfonso Cuaron's son) shot a short film that shows the other side of the conversation that Sandra Bullock's character had while in the Soyuz capsule. In the film, an Inuit fisherman struggles to communicate with the distressed voice on the other end of his radio.
The short was filmed "guerrilla style" on location on a budget of about $100,000 -- most of which went toward the 10-person crew's travel costs -- and Cuaron completed it in time to meld the dialogue into Gravity's final sound mix. The result is a seamless conversation between Aningaaq and Ryan, stranded 200 miles above him, the twin stories of isolated human survival providing thematic cohesion. Still, Jonas says he was careful "to make it a piece that could stand on its own." Should both get Oscar noms, an interesting dynamic would emerge: Two films potentially could win for representing different sides of one conversation, to say nothing of having come from father and son.
Also interesting is that Visitors is comprised of only 74 shots, which with a runtime of 87 minutes means the average shot lasts over a minute. According to a recent investigation by Adam Jameson, an ASL (average shot length) of more than a minute is unusual in contemporary film. Inception, for instance, has a ASL of just 3.1 seconds and even a film like Drive, with many long shots, has an ASL of 7 seconds. But as Jameson notes, Alfonso Cuarón's upcoming Gravity contains only 156 shots, including a 17-minute-long shot that opens the film. But the Hollywood master of long-running shots? Hitchcock, I presume:
1. Rope (1948, Alfred Hitchcock), ASL = 433.9 [seconds]
OK, this isn't a recent recent film, but it has to be noted, as it's most likely the highest ASL in Hollywood. Hitchcock used only 10 shots in making it (the film's Wikipedia page lists them). (As you probably know, Hitchcock designed those shots, then edited them such that the finished film appeared to be a single take.)
