Gwyneth, her mom, Blythe Danner, her (boyfriend?/husband?) Chris Martin, and Jake Gyllenhaal sat directly in front of me for awhile during the filming of Proof. Gwyneth seemed to be in character during most of the filming. (somber mood) as it was filmed in the Rockefeller chapel for a memorial scene. She was very nice and she and her mom obliged us with autographs. This scene was filmed on 10/8/03 and the crew finished filming at the University of Chicago on 10/10/03. One of the producers mentioned that they will film for another week in Chicago, then go back to London to film the rest of the filming.
