There could be many interpretations. Maybe Charlie was involved in a situation where he was wrongly accused, and then the truth came out, which is the 'true story' part. It might be a story of redemption or a discovery of facts that changed people's perception of Charlie.
If 'sorry charlie based on a true story' is a story, perhaps Charlie is a person who has faced some kind of misfortune or made certain choices that are being told in the context of real - life events. It could be about his relationships, his career, or some other aspect of his life that has been fictionalized to some extent while still being rooted in truth.
Suppose Charlie was in a relationship. His partner thought he was unfaithful because of some misunderstandings. But when the truth came out, the partner said 'sorry Charlie'. This could be one way to illustrate a 'Sorry Charlie True Story', where misinterpretations lead to apologies once the truth is known.
I'm not sure specifically what this refers to. It could be a local or niche story that not many people outside of a certain area or group know about. Maybe it's a story that has been passed down in a community and is now being shared more widely as 'based on a true story'.
Yes, it is. 'Charlie Charlie' is often claimed to be based on a true story, which involves some sort of supernatural or spiritual encounter with an entity named Charlie. However, there's no scientific proof to back it up.
