Often when a movie or a story is said to be 'based on a true story', it means it draws inspiration from real - life events. In the case of 'That's My Boy', it might be centered around a family in a particular situation.

It could also involve some sort of local or cultural aspect that makes the story unique and real - life - inspired.
Yes, it is. The idea of basing it on a true story helps to set the mood. It allows the filmmakers to play on people's fears of the unknown that might be associated with real - life events. The true - story aspect can also make the audience more invested in the movie as they try to figure out which parts might have actually happened.
