Continuity mistake: After the first time the mother disappears from the family photo, and the father and son are talking after the father "saves" the first nurse, there is a wide shot of the board with the family picture on it - and it shows the mother in the picture. When the camera zooms in on the picture, the mother is gone again.

Continuity mistake: At the very end when the family and friends are playing baseball in the park, the first ball Frank hits smashes into the headlight on Gordo's Benz.

But when the next shot of it is clear, it says "1YAHOO".
Continuity mistake: When Frank has survived the Buxton fire and is trying to reach his son in the future over the radio, his son from that time walks in and sits on Frank's knee.
