My daughter, who lives in Philly, gave me the "homework" of watching this movie before coming to visit her next month. The three guys are sort of innocent and determined, especially Justin Doerr. The neighbors of the mysterious and paranoid Philadelphian who may have left the tiles on the asphalt of Philly and other cities are earnest and protective of the man's privacy. There are weird-beard short wave radio enthusiasts. Larry King and David Mamet enter into the game. Nonetheless, you can take it to the bank: whatever Toynbee or Kubrick said, you cannot resurrect the dead on Jupiter.
