Actor Salman Khan reacted to the film's clash with his film Sikandar by stating he loved Mohanlal as an actor and he knew it would be an excellent film. Incidentally, Khan had previously starred in Godfather, the Telugu remake of Lucifer.
Empuraan was filmed using the anamorphic format with a 1:2.8 aspect ratio, ensuring visual consistency with the first film, Lucifer. Prithviraj confirmed the third installment will follow the same approach.
The film was shot for 14 months across eight Indian states and four countries, including the UK, USA and UAE.
Despite the scale of the film, the cast and crew, and the narrative, Empuraan was completed in 145 days, which was 28 days lesser than the originally planned schedule.
The initial plans for the Lucifer film franchise were to be conceived as a 12-episode television series rather than a trilogy of films as told by director Prithviraj Sukumaran.
