There's no question this must be excruciatingly difficult on the entire family.

This is so sad.
Melissa's brother, Dirk Mathison, confirmed that the cause of her death was neuroendocrine cancer.
Even though Miz Mathison's life was cut short, she had quite a few accomplishments to her name.
Not only did she write and serve as associate producer on E.T., but she also wrote screenplays for Martin Scorsese's Kundun, as well as The Escape Artist, and The Black Stallion.
Mr. Spielberg released a statement regarding Melissa's passing saying:
"Melissa had a heart that shined with generosity and love and burned as bright as the heart she gave E.T."
The Hollywood screenwriter was also married to Harrison Ford from 1983-2004 and had two children with the actor — Malcolm and Georgia.
Our hearts go out to those affected by this tragic loss.
