Also depends on what sort of an image Barun wants to create!!
If he wants to be popular with the common masses..it'll be hard..because the charm that Shahrukh..Amir or Salman brings with them..or even Saif...that hold the audience captive from Kashmir to Kanyakumari..that would be highly impossible!!
But Bollywood has "actors" too..Irrfan Khan,Nawazuddin Siddique,Konkona Sensharma...there are handful of people here and there...making their presence felt!!This breed of actors do not need to dance around the trees or wear Hawai T shirts in the mountains of Switzerland to prove their acting talents!!
Among the newer lot..Aamir's Nephew Imran Khan..is a horrible dancer.And he has confessed that!!But being Aamir's nephew..he has producers lined up at his door!!So for a struggler like Barun..without any contacts as such..it'll be hard..but not impossible!!
And Bollywood cannot be defined by a few adjectives!!I defy to agree with a few here.If convention rules BW..there are also many who refuses to get stereotyped and are purely unconventional!It is a wide arena..and everyone gets a fair share..ofc with a few good qualities!!
