This was the first Indian film to feature 7.1 surround sound at standard resolution.
The theatrical cut of the film is available only on an international DVD version. The internet version is heavily cut.
This film opened in 500-odd screens across Tamil Nadu - the widest release ever then in the careers of both the director Ameer Sultan and the lead actor Jayam Ravi.
Director Ameer Sultan's cameo is in the end credits song. It was used to promote the film on television.
The film was originally titled Aadhi Bhagavan, but the censors ordered the makers to change the title to Ameerin Aadhi-Bhagavan in order to denote two separate characters. Aadhi Bhagavan refers to God's name.
