1. History of 3D Film.

2. Bwana Devil
 Known as the first feature-length
3D film. Released in 1952. It
had the slogan “A lion in your
lap! A lover in your arms!
 The movie earned $2.7 million
in rentals in North America in
1953. The film was a critical
failure, but a runaway success
with audiences.
 The audience wore 3-D glasses
with grey Polaroid filters.

3. Bwana Devil
 You can see from the picture on
the right that it was a massive
thing to go see a 3D film, people
are dressed in suits and
dresses, now everyone goes to
the cinema dressed casually.
 Bwana Devil’s ‘Natural Vision’
sparked interest in other
directors such as Alfred
Hitchcock who created his own
3D Film ‘Dial M For Murder’ in
1954. More 3D films were made
during this boom period.
 For the most part, studios
seemed to gravitate towards
horror movies when it came to
3D.

4. Decline in popularity
 Despite these advances, 3D
movies fell out of popularity
by the middle of the decade.
The reasons for the decline
were mostly technical.
 3D projectors required two
reels to be displayed in
perfect synchronization.
Small errors in
synchronization could easily
lead to eye strain and
headaches among viewers.
 Keeping reels in good repair
was also an ongoing
concern.

5. New ideas
 3D's second renaissance came
 A company called Stereovision
some time later when producer
Arch Gobler found a way to
eliminate the need for dual-reel
movies.
developed another new
technology in 1970.
Stereovision's 3D format
displayed reels side-by-side on
a single, anamorphic film strip.
 His new technique, Space-
Vision 3D, worked by overlaying
two stereoscopic images on a
single reel. As long as reels
were spliced properly during
printing, viewers no longer
needed to worry about syncing
issues.
 Many of these films in the '70s
and '80s were marketed
squarely at older viewers and
fans of violent horror films.

6. Criticisms
 Late film critic Late film
critic Roger Ebert
repeatedly criticized 3D
film as being "too
dim", sometimes
distracting or even
nausea-inducing, and
argued that it is an
expensive technology that
adds nothing of value to
the movie-going
experience (since 2-D
movies already provide a
sufficient illusion of 3D).
 A Film critic argued that
3D adds "not that much"
value to a film, and said
that, while he liked Avatar,
the many impressive
things he saw in the
movie had nothing to do
with 3D.
