The title character name is inspired from a character name from Mani Ratnam's Kannathil Muthamittal (2002)
The sound from TV channel used in the trailer 1 of Amutha is actually from P.S. Arjun's own short film titled 'Zugzwang'.
P.S. Arjun began writing the script of 'Amutha' in 2016. He wrote the introduction and climax part first and then added multiple story lines.
The film took twenty-one days to shoot.
