Trust Aamir Khan to delve deep into his characters for any film. After painful piercings and growing long hair for ‘Thugs of Hindostan’, the actor is now sporting a heavy-beard look for his next. Aamir recently returned from an international holiday and will soon plunge into preps for his upcoming film, ‘Lal Singh Chaddha’, which is a remake of the Oscar-winning Hollywood film ‘Forrest Gump’. In the Hindi flick, Aamir plays a character who will travel through important historical events of India. While he is slowly getting into the look of the character, the actor will soon start full-fledged preparations for the movie. ‘Lal Singh Chaddha’ will be directed by Advait Chandan, who has previously directed ‘Secret Superstar’, featuring Aamir.
