Corrected entry: A phone call comes through on Grady's secret cell phone once his fiancee, Gray, is staying in his room. From everything we've seen this is at least a few weeks after Grady's death, and nobody knew about the phone, yet the screen shows a fully charged battery.
Catch and Release (2006)
1 corrected entry
Directed by: Susannah Grant
Starring: Jennifer Garner, Timothy Olyphant, Kevin Smith, Sam Jaeger
Continuity mistake: In the scene where Gray has just come in to see the mother of her dead fiance's son in the house, the boy is throwing things everywhere. He stops by the TV and begins to pull CDs from the shelves into the floor. He pulls all the CDs off the shelves, but every time it cuts back to him, there are plenty more CDs for him to pull down.
Correction: This wasn't a cell phone, and it was on a base hence the full 'charge'.
