Corrected entry: At the end when Mitch and friends are driving the herd through the river, there is a terrible rainstorm. However, several times, especially when Mitch is in the river, you can see the sun shining and casting shadows all around. That was one crazy rainstorm.
Corrected entry: Near the end of the movie, Mitch, Phil and Ed ride up to the ridge together and look at the ranch below (where the cattle are to be delivered). Notice their faces: while Mitch and Phil have plenty of stubble Ed is clean shaven. Given their circumstances (lost in the wilderness, major rainstorm, no food supply) it seems odd that Ed would be concerned about shaving....
Corrected entry: When Mitch's boss complains about the 'Pizza Time' commercial, he remarks: 'No, but you bought it.' Radio stations don't buy commercials. Companies buy air time from radio stations. Mitch even explains this to his son's class.
Corrected entry: During the scenes of the cattle drive, Mitch and the boys are riding in the middle of the herd, with the cattle all around them. In reality, cowboys ride around the outside of a herd. Riding in the middle looks good for a movie, but in real life would scatter the cattle in every direction.
