Continuity mistake: In the scene at the hospital in which Weevil is lying in the hospital bed, he has his legs bent to the side so they are obscured from view at first, but then when the camera changes angles, his feet are fully extended to the end of the bed. (01:02:00 - 01:04:00)
Factual error: When Piz is at the New York radio studio, the microphone is labeled WBEZ 91.5 which is NPR in Chicago, not New York. (04:30:00)
Continuity mistake: In the scene where Logan carries Veronica into her room and covers her with the blanket, she is fully clothed. When she comes out to ask him, "don't go," and then kisses him, she is not wearing pants and has a different shirt.
Factual error: In the Logan departure scene near the end of the movie, Logan's naval officer uniform is missing his rank shoulder boards.
Other mistake: Spoiler... When Stu Cobbler (Martin Starr) is revealed as the murderer, he goes to Gia's apartment to kill Veronica. Upon entering, Cobb has to disable an alarm with a digital touch pad, requiring the use of his fingers. However, he uses the metal barrel of the gun.
Suggested correction: Touchscreens don't need human skin to work. Capacitive touch screens just need something conductive (that's how touchscreen styluses work), and metal is conductive (albeit likely scratching the screen). But you also get resistive touchscreens, which simply detect pressure, and anything works on them.
