The health condition of veteran actor Soumitra Chatterjee continued to be "critical" on Wednesday, though his parameters are normal, doctors attending to the thespian said.

The 85-year-old Dadasaheb Phalke awardee is in a "confusional state", they said.

"Stable. Slept well. All parameters normal. Sodium high only. But critical," they said.

The legendary Bengali actor has been suffering from fever since Sunday afternoon, following which doctors are now planning to conduct another test on Wednesday to check whether it is due to the COVID-19 infection.

"Chatterjee is still in a confusional state which is progressive in nature with COVID-related encephalopathy and metabolic encephalopathy. He continues to be restless, arousable and has mild agitation and involuntary limb movements but no focal or generalised seizure event occurred," they said.

The critically acclaimed actor, who has the rare distinction of having worked with maestros like Satyajit Ray, Mrinal Sen, Tapan Sinha and Tarun Mazumdar, was admitted to a private hospital here on October 6 after he tested positive for COVID-19.

He had to be shifted to the ITU as his condition turned critical. A team of 15 doctors is overseeing him at the hospital.

Chatterjee had resumed shooting a few days ago. Parambrata, another noted Bengali actor, completed the shooting of Abhiyan under his direction. Jisshu Sengupta will be seen playing the role of young Soumitra in the film. Soumitra himself plays his older self in the film.

Chatterjee, a celebrated Bengali actor, is best known for his collaboration with Oscar-winner Satyajit Ray and the Feluda series. Soumitra immortalised the titular role of Feluda in Ray's films.

He was a part of several other works of Ray, including Apu'r Sangshar or The World Of Apu. Some of Chatterjee's best works include Ashani Sanket, Ghare Baire, Aranyer Din Ratri, Charulata, Shakha Proshakha, Jhinder Bandi, Saat Pake Bandha, and more.
