This little slip-up happens right after they find out the little boy's mother has died. John Cusack's character bends over the recently deceased woman. If you'll notice, he has a five o'clock shadow. This is plausible, since he's obviously had a long day with no time to shave. The camera cuts to the mother or someone and then cuts back to Cusack. If you'll notice, his stubble is all gone. So how did this guy have enough time to get a shave in with all these things going on?
