How to Make a Movie Like Don (1978)

Take these scripts of the movies in a grinder. And voila you are a Salim Javed! 

1. Mr. India (1961)
2. Salaam Memsahab (1961)
3. China Town (1962)
4. An Evening in Paris (1967)
5. Naseehat (1960s, approximate based on context)
6. Kaalicharan (1976)
7. Chhailla Babu (1977)
8. The Double Man (Hollywood film)

Each of these films seems to revolve around themes of mistaken identity, double roles, or undercover missions, similar to Don’s storyline.
