Screen icon Audrey Hepburn makes a poignant cameo in Spielberg’s Always. It was her final film performance.

In this letter, written by Spielberg to Hepburn as the movie was nearing the end of principal photography, Spielberg offers her the role of Hap, an angelic presence who guides Richard Dreyfuss’s Pete on his journey into the afterlife.

It’s a sweet and very genuine note, and for fans of the film, it offers the interesting tidbit that Hap was originally written as a man.

The letter was auctioned in September at Christie’s.
