A source close to the development says: "'Iron Man' has had some great soundtrack for all the instalments that have released. Classic among them is Black Sabbath's cult hit 'Iron Man'.
The idea, which is being developed, is to merge all the classic soundtracks and background score and release as an album as a tribute to 'Iron Man'."
"'Iron Man 3' is set to release April 26 in India and interestingly, it looks like Indian band Agnee will be part of the ensemble collector's edition," the source added.
Agnee had composed the official Hindi soundtrack "Hello Andhero" for the "Avengers" that featured Iron Man.
Directed by Shane Black, "Iron Man 3" features Robert Downey, Jr., Gwyneth Paltrow, Don Cheadle and Guy Pearce, among others.
