The film was re-released in 2013. This is the only colour movie in the franchise and also the only movie in the franchise to not feature Narasimharaju. The movie was dubbed in Hindi in 1983 as Jasoos 999. A fifth movie in the franchise titled Operation Golden Gang was announced but dropped owing to average response to this movie coupled with high budget for the sequel. This was also the first film of the franchise to have a male playback singer.

The movie was shot in Nepaland became the first Kannada movie to be shot outside India. However, another Kannada movie which released four months later, Singaporenalli Raja Kulla is widely credited as the movie which started the trend of Kannada movies being shot outside India since it was shot in a country which is not an Indian neighbour.
