Vikram made a name for himself as great actor with films like 'Sethu' and 'Kaasi' but he did not reach all classes of the audience.  It was then that Saran approached Ajith to play the lead of a golden hearted rowdy in 'Gemini' which he could not do due to various reasons.  Saran then approached Vikram who grabbed the opportunity with both hands and helped him become a mass hero.  Ajith was the first choice for Vikram's other blockbuster hit 'Saamy'.

Arya, generally having a chocolate boy image got his breathrough role in 'Naan Kadavul' directed by Bala which catapulted him into the big league.  The behind the scenes news is that the project was initially announced with Ajith in the lead who walked out after creative difference with the director.
