La patrulla del peligro

According to Dan's ledger, after his apprenticeship where he made $15/day working 5 to 6 days per week, he is making $40 per day - about ten times what the average blue-collar worker was making at the time. And that $40 would equate to around $776 in 2021. This astronomical amount for the time reflects the danger of the job and the probable fact that few men would be willing to take the job.

About 14 minutes into the movie, Sam & Dan are having a beer at a bar. When the camera is showing the two from the front, Sam's beer is about half empty but when there is a shot from behind the two, Sam's beer is empty. These exchanging camera shots reveal this mistake 2 or 3 times.
