Mehra, known for writing and directing films like `Rang De Basanti`, `Delhi 6` and the recently released `Bhaag Milkha Bhaag`, too lauded `Kolaveri di` fame actor-singer Dhanush. “Dhanush is born to give happiness. More than acting, I think his religion is to spread happiness. He makes me very happy all the time,” Mehra said here. “If I have the script, we can get together! Why not?” he added.
