Based on the actual life of Reliance Industries co-founder Dhirubhai Ambani, Guru is a Indian drama film directed by Mani Ratnam and starring Abhishek Bachchan and Aishwarya Rai. It premiered at the Cannes Film Festival in 2007 in the World Cinema categroy.
Guru tells the story of Dhirubhai Ambani, starting from his early life as a young boy in a poor village. The film chronicles his attempts to make a name for himself as he grows older, eventually delving into shady deals to keep climbing. The film ends with him facing charges of corruption.
Guru was critically acclaimed, receiving an exceptional score of 90% on Rotten Tomatoes. Critics praised Abhishek Bachchan's performance especially, with one critic saying: "Guru is fuelled by a slew of strong performances. Abhishek Bachchan owns the movie, forcing audiences to sit up straight as it begins and making us laugh and applaud as he carries on. He's impressive in every frame, as he ebulliently takes over an alien room by hopping onto a chair, or when he's trying to be ever so slightly slimy, polishing his spectacles and showing off his smarminess."
