A documentary shot by filmmakers all over the world that serves as a time capsule to show future generations what it was like to be alive on the 24th of July, 2010.
What would happen if you invited the entire planet to pull out their video cameras, cellphones, or other tech toys of choice and simultaneously grab footage to post on YouTube? Would you get a broadly representational portrait of cultural routines, disparities, and commonalities in the post-millennial world? Or would the picture feel skewed, weighted toward a socially networked global community increasingly able to indulge an all-about-me ethos? The answers lie in “Life in a Day,’’ an ambitiously experimental, “user-generated’’ documentary shot on July 24 of last year, and spearheaded by director Kevin Macdonald (“The Last King of Scotland’’).
