The Kalapani region has been a matter of territorial dispute between Nepal and India. Kalapani is an area rich in natural resources. Historically, issues regarding its border demarcation have led to diplomatic tensions. Nepal claims that India has occupied parts of Kalapani which belong to Nepal according to historical treaties and geographical facts. This has led to various diplomatic discussions and negotiations between the two countries over the years to resolve this long - standing territorial issue.
Kalapani is indeed based on true events. The creators drew from actual occurrences to shape the narrative, making it a compelling tale with a real-world connection.

The Phoenix Malayalam movie is not based on a true story. It's a work of fiction crafted by the imagination of the filmmakers. They might have drawn inspiration from various sources, but it doesn't have a real-life basis.
