The film was planned as a multilingual film in Malayalam, Telugu and Tamil and although the Tamil version were dropped in favour of a dubbed version. Krishnam is based on a real-life incident that started when Akshay Krishnan from Thrissur faced an accident during a dance contest. He was diagnosed with a hernia during the incident. However, that was not the only issue as his entire stomach cavity and body was filled with water. His kidney, liver, lungs and spleen was damaged. Several overseas doctors couldn't find the root cause of his problem but a doctor from Thrissur checked out his heart and realized that he had a rare heart condition. The film's relationship to Krishnan is that his father is a devotee of Guruvayurappan and after the incident, Akshay Krishnan's devotion in god increased. After shooting was complete for Krishnam, the film was partially reshot in Telugu as Dear Krishna, which began production in 2018.

The film's music is by Hariprasad R.
