Revealing mistake: The appearance of the buildings/scenery opposite of FBI Director Gabriel Robinson's office vary, indicating the occasional use of a "green screen." The angles are inconsistent (wider or in the opposite direction) and sometimes grass and/or trees can be seen where the avenue between the buildings should be visible. (00:10:05 - 00:10:38)
Revealing mistake: When Travis was talking to his daughter Amanda at his granddaughter's birthday party, the background scenery was inconsistent (indicating use of a green screen). Some objects (e.g, brown hanging lampshade? And balloons) should have been visible when they were not and/or were in different locations. Balloons that were to the left of the screen near Amanda "disappeared" in wide front shots. (00:13:05)
Revealing mistake: When Travis arose from the couch, "Little Man" - sleeping right next to him - did not move at all or even open his eyes, which would be extremely unlikely for a "real" dog; the dog, though appearing to be "breathing", was fake. (01:17:30)
