Heavier Than Heaven is a 2001 biography of musician Kurt Cobain, the frontman of the grunge band Nirvana.

For the book, Cross desired to create the definitive Cobain biography, and over four years conducted 400+ interviews; in particular, he was granted exclusive interviews and access to Cobain's private journals, lyrics and photos, by his widow Courtney Love.

[3] At the same time, Cross' desire for the book to be as complete as possible meant that he occasionally accepted secondhand (and incorrect) information as fact.

David Benioff was hired by Universal Pictures in October 2007 to write a screenplay based on the Charles R. Cross biography.

[5] Courtney Love was to serve as executive producer with Marc Forster showing interest in directing.
