Martin Scorsese was presented with an earlier cut of the film. In his letter he refers to the film as "Bug Who Carries Fire" which was the working title at the time.
Dear Khyentse,
I saw your film "Bug Who Carries Fire." Thank you for getting a copy to me.
Such a beautiful movie. Sweet, sad and moving. I hope you do well with it.
Let me know what's planned for it... release, etc.
Thank you again; I'm an admirer of your work as I'm sure you're aware.
All the best for the future.
Martin Scorsese
