A new reality show in the Czech Republic has let a family of seven experience what it was like living under Nazi occupation during World War II. The Czech public broadcaster said the family members, chosen from 400 applicants, were brought back in time to March 15, 1939 — the day Hitler’s troops took over the country. The goal was to show what common people had to get through at the time and historians and architects made sure their experience was as authentic as possible.
