Casablanca (1942)
Thus Casablanca is not just one film. It is many films, an anthology.
[...] When all the archetypes burst in shamelessly, we reach Homeric
depths. Two clichés make us laugh. A hundred clichés move us. For
we sense dimly that the clichés are talking among themselves, and
celebrating a reunion.
Umberto Eco

The Technical Dimension
Produced by Warner Bros. at the height of the Hollywood studio system,
Casablanca embraced what is now known as "invisible style." Rather than
dazzling the eye with eye-catching visuals and histrionic acting, it seduces the
viewer by creating a seamless, lush universe that gradually envelops the
audience. Hardly an effortless accomplishment, "invisible style" required an
absolute mastery of the various cinematic elements by its collaborators,
including Hungarian director Michael Curtiz (Mildred Pierce, 1945), director
of photography Arthur Edeson (The Maltese Falcon, 1941), Art Director Carl
Jules Weyl (The Big Sleep, 1946), composer Max Steiner (Gone With the
Wind) and soon-to-be-director Don Siegel (Dirty Harry, 1972), whose dynamic
opening montage invests the film with a sense of political urgency.

“Casablanca” is a prime example of the “Invisible Technique” of the
Hollywood Studio System, in which camerawork and lighting and editing are
meant to subtly support the story rather than being abrasive or even
noticed. So unlike Soviet Montage (“The Battleship Potemkin”), the edits and
transitions are meant to be smooth and seamless. Unlike German
Expressionism (“The Cabinet of Dr. Caligari, “ “Sunrise”), the design and
lighting are meant to reflect reality, be it a stylized reality, rather than be an
expression of an artist’s view of the world.

The production design of Casablanca has come to represent the aesthetics of
romantic longing. Its smoky casino, fog-shrouded runway, trench coats,
potted palms and gruff-voiced pianist repeatedly surface in contemporary
films, commercials, television programs and even restaurant decor as
respects are paid to this quintessential Hollywood classic.

The Dramatic Dimension
Melodrama – A dramatic work that exaggerates plot, crises, and
characters in order to appeal to or manipulate the emotions, and
often depends on stock characters or stereotypes for effect, as
opposed to “realistic” conflict and emotions.
A drama involves primarily a conflict of values within a man (as
expressed in action); a melodrama involves only a conflict of man with
other men.

The Reluctant Hero
The hero may refuse the adventure or deny the ability to move beyond the status quo.
The heralded event may even be ignored – All of these constitute the ‘Refusal of the
Call.’
The use of magical intervention is then needed to plunge the hero into the unknown.
The reluctant hero requires supernatural forces to urge him on, while the willing
adventurer gathers amulets (magical items) and advice from the protector as aid for
the journey…
The reluctant hero loses all desire to abandon his bliss, he does not want to take on the
burdens of the world. Someone or thing may facilitate his miraculous return from
apparent death. An overriding reason is necessary to bring the hero back to the world
to save it.

A May 21, 1942 letter from Joseph I. Breen, director of the Production
Code Administration, to Warner Bros. executive Jack Warner objects
to the portrayal of "Renault's" practice of seducing women in
exchange for exit visas. The PCA also objected to the "suggestion that
Ilsa was married all the time she was having her love affair with Rick in
Paris." Later, Breen warned that the script should not imply that "Ilsa"
slept with "Rick" when she comes to beg for the letters of transit.

Vichy
Germany occupied France
from 1940 to 1944. The spa
and resort town of Vichy,
famous for its water, was the
de facto capital of the
collaborationist government.
The audience of 1943 knew
the man pictured here. He
was Marshal Henri Petain, the
pro-German dictator of
France, and Capt. Renauld's
ultimate boss.

Propaganda
Irene Lee, Warner Brothers’ West Coast Story Editor, submitted the script to
producer Hal Wallis four days after the attack on Pearl Harbor.
Warner Brothers ordered a hasty rewrite of "Across the Pacific" which
involved a Japanese plot to blow up Pearl Harbor, changing the setting to
the Panama Canal.
Hollywood had a history of supporting and being supported by Roosevelt
and his administration.
The Warner Brothers had bucked the other studios, hesitant to alienate
foreign markets, by releasing “Confessions of a Nazi Spy” in 1939.
In September of 1941, isolationist members of the U.S. Senate, calling
Hollywood “a raging volcano of war fever,” launched an investigation into
whether studio executives, many of whom were Jewish, were inserting
interventionist messages into popular movies.

Propaganda
How does “Casablanca” act as propaganda during the U.S. involvement
during World War II?
Is Rick Blaine, at first hesitant to get involved, eventually pushed to take
action, a metaphor for the U.S. and its hesitation at the outset of World War
!!?
Made in 1942 and released not long after the United States had seriously
committed itself to fighting in World War II, the classic film Casablanca
provides insight into popular attitudes early in the war. In addition, it lays
out some of the arguments for U.S. involvement, tracing the transformation
of U.S. policy from neutrality to non-belligerency to involvement. The
character of Richard "Rick" Blaine, played by Humphrey Bogart, provided a
heroic analogy for the historical process of U.S. involvement in the war

http://www.riebel-roque.com/cas.html
The Historical Dimension
The film premiered in New York City in November 1942, in what was called a
pre-release engagement. This showing was rushed to theaters to capitalize
on the recent events in North Africa, specifically the invasion of American
troops into the real Casablanca.
It opened on Thanksgiving Day, following a parade up Fifth Avenue of Free
French leaders, when the Free French flag was unfurled for the first time in
the United States since the fall of Vichy.
Because this kind of free publicity happens only once in a blue moon,
Warner Bros. rushed Casablanca to just one theater in New York. But it was
not seen by the rest of the country until early 1943, including Los Angeles.
As luck would have it, the national release coincided with another
Casablanca event, a summit meeting between President Franklin D.
Roosevelt, Winston Churchill, and Joseph Stalin.
The Historical Dimension
Perhaps the greatest praise came from London, where General Charles de
Gaulle, leader of the Free French forces, requested a print of Casablanca for
a special showing to his staff.
