I heard the local wannabe heros (or wannabe villains) were taunting Shakti Kapoor for a duel when he came to Kathmandu to shoot a movie called Mahaan (with Amitabh, Gabbar Singh, Amjad Khan, etc.) So this is not a 90's only phenomenon, apparently it happened in 80's too, and I am sure it happened back in 60's or 70's when Dev Anand came to film his hippie movie with Zeenat Aman (forgot the name of the movie).
