Kangna has no qualms about doing bold scenes in Gangster, Who Lamhe, Fashion, Life in a Metro or Raaz- the mystery continues, but for a scene in Once upon a time in Mumbai , Kangna was very nervous when Ajay expressed his emotions with his intense eyes.
Kangna felt inferior as she has really small eyes and they are not as expressive as Ajay.
Kangna felt it was too challenging for her and she really faced difficulty in acting opposite Ajay.
But it must have been a real time experience for Kangna to act opposite Ajay Devgn. Once Upon a time in Mumbai also stars Emraan Hashmi, Prachi Desai.
