My reasoning behind this is quite simple; there isn't room for two Salman Khans in Bollywood. When a newcomer debuts, there better be some uniqueness about them in order for them to stick out and become a staple on screen. The confusion that will lead to sharing a name with a currently popular actor is a big drawback. The comparisons would be inevitable and never-ending, even if dancer Salman doesn't resemble much like Bollywood Salman. That is a lot of pressure to put on a new-comer, not to mention the backlash he might receive.
I remember in Elementary school when we had two classmates sharing the same name, we'd always come up with ways to differientiate them (sometimes calling them by their last names) I was told it is highly an inconvience on those students as one of my friend has faced similar situation. She would cringe everytime some kid would come up with what he considers a clever way to differentiate her (long-haired Amy, short Amy, smart Amy, etc)It wouldn't have been a big deal if Bollywood Salman wasn't relevant today, but he is. I'm not completely sure if Bollywood is Salman's target but if it is, the road ahead might prove to be difficult. Stars like Salman Khan, Amir Khan, SRK, etc have been around for a long time. It took years to win the hearts of their enormous worldwide fanbase. Making it in Bollywood is a daunting task. Perseverance, talent, attitude and LUCK goes a long way but a name is like your label. It plays a significant part in how people react to you albeit how unfair it might seem.
That being said, something like a name might seem trivial to many of us. I mean, a rose by any other name would smell just as sweet, right? But that's not the case in the entertainment industry.
