Tobey Maguire was at the WGBH studios Wednesday, but, alas, not to sit down with Emily Rooney on “Greater Boston.” The actor was there to shoot a scene for “Labor Day,” director Jason Reitman’s film based on Joyce Maynard’s book. Maguire filmed a scene with actor Gattlin Griffith, who plays the younger version of Maguire’s character. We’re told the crew cleared out in time for Rooney to tape Wednesday’s episode of “Greater Boston.”
