After the death of this actor, Ray once remarked that there will be no further movies in the Feluda series as Jatayu cannot be thought of without Santosh Dutta.

Though after the death of Ray, the role of Jatayu was later played by artists such as Anup Kumar, Bibhu Bhattacharya, and even Rabi Ghosh.

In Hirak Rajar Deshe, which is a sequel to Goopy Gayen Bagha Bayen, Dutta played the role of a mysterious scientist (known as Gobeshok Gobuchondro Gyanotirtho Gyanorotno Gyanambudhi Gyanochuramoni), in addition to a small appearance for the same 'King of Shundi'.

Dutta played important roles in films like Teen Kanya, Paras Pathar, Kapurush O Mahapurush, Streer Patra, Marjina Abdallah, Jana Aranya, Char Murti and Gana Devata.

He worked in a TV serial called Goenda Bhagabandas with Rabi Ghosh, another famous actor of his time.
