Didn't Kubrick have a similar idea at one point?
There were rumors (apparently started by Dark Horizons) that Kubrick was secretly shooting A.I. in bits and pieces over a period of several years, with Joseph Mazzello in the lead role. (This was before anybody had really solid details on what the storyline of A.I. would be.) As it turns out the rumor was false; it came about because Kubrick had Mazzello under contract for two years because he wanted him to star in Aryan Papers, a Holocaust drama that never got off the ground for various reasons.
On a somewhat related note, Lars von Trier has shooting a film in three-minute chunks every year since 1991 called Dimension; it's supposed to be done in 2024. I have no clue what it's about.
