Since we have so little information, it's possible that 'the great blank' was a creative or experimental title for a novel in 1925. It could have been a work that explored new themes or literary forms for that era, but without further research, we can't be certain.
It could be based on real events, but it might also have fictional elements mixed in. Sometimes movies or stories draw inspiration from real-life but take creative liberties.
No, it's not a true story. It's a fictional film that presents a gritty portrayal of life in a particular neighborhood, but it's not based on actual events.
The movie Snow on tha Bluff claims to be a true story. It incorporates real-life situations and characters, but like many films based on true events, there could be some artistic liberties taken to make it more engaging for the audience.
