Mission to Moscow is a 1943 drama directed by Michael Curtiz, and book of the same name by Ambassador Joseph E. Davies.

The movie, starring Walter Huston, was made in response to a request by Franklin D. Roosevelt, and is one of the movies famously targeted by the House Committee on Un-American Activities. It chronicles the experiences of the second American ambassador to the Soviet Union.

The Book

Joseph E. Davies wrote a memoir about his stint as ambassador in 1941. This book is the basis for the film Mission to Moscow. While the storylines of both the book and movie are practically identical, the movie uses cinematic techniques and dialogue changes to overstate or change some controversial points in the book - changes that were made with Davies' approval.
