Kaalpurush or Kalpurush (English name: Memories in the Mist) is a 2005 Indian Bengali drama film directed and written by Buddhadev Dasgupta.

The film stars Mithun Chakraborty and Rahul Bose in lead roles.

Rahul tries to reconnect with his long-lost father (played by Mithun Chakraborty), while Sameera dreams of breaking free of her stifling domestic life.

While a devastated Mithun becomes a footloose traveller, their son bears the scar for the rest of his life.

Battling the brunts of a society that defines success too materialistically, Rahul also continues to relive his childhood memories.

His wife, Sameera, meanwhile flies to the United States to spend an extended holiday with her brother's family settled there.

He spends a memorable day with his father, reliving their memories, as well as discussing many aspects of life.

However, the duo appears several times in the film, especially in the moments when there is a voice-over of Mithun, or when Rahul is reliving some old memories.
