Sound is also rather complicated. A variety of formats have evolved over the years, but the capabilities of individual theatres and home video systems varies greatly.
Let's start at the very beginning. A vey good place to start. So-called "silent" films were never really silent. They were intended to be accompanied by live music. In the largest big city theaters this might involve a full orchestra. Small town theaters usually had only a piano, perhaps with a violin player alongside. However, most theaters of the silent era were equipped with a theater organ, which enabled a single musician to have a full range of instruments, including percussion and sound effects, at his fingertips. The better quality videos of silent films feature an organ or orchestral soundtrack composed specially for the film and recorded in stereo. Cheap videos typically insert generic music that is not synchronized with the action.
Experiments in sound actually began as early as 1896 when a presentation was made in Berlin using phonographic discs synchronized with the film. Over the next 30 years a number of short films and newsreels were made with sound, but none had widespread exhibition. Sound finally become commercially successful in 1927 when Warner Bros. introduced a sound on disc system called Vitaphone for the first "talkies." The following year Fox studios offered the first "sound on film" process which they called Movietone. Soon after, Warners abandoned the disc format in favor of sound on film. By the middle of 1930 silent films had been phased out.
Stereo sound first came along in 1935 when the silent film Napoleon (1927) was reissued with a new soundtrack for a special engagement in Paris. Films with stereo sound were produced in the U.S. beginning in 1940. Disney Studios developed the first "surround" stereo in 1941 for Fantasia, but Fantasound, as the system was called, was installed in only a handful of theaters. In the early 1970s Dolby Laboratories developed an economical method of encoding four channels of stereo information onto a standard two-channel stereo soundtrack. Theaters equipped with special decoders could present Dolby Stereo offering right, left, center and surround channels with relative ease. A later version, Dolby SR offered greater sound clarity, less noise, and a wider frequency range.
The next upgrade was digital sound with as many as six channels, and in this arena Dolby Digital has a competitor known as DTS (Digital Theater Systems), which resulted in some crowded real estate on the film. The Dolby Digital soundtrack is located between the sprocket holes on the film. DTS actually revived the sound on disc concept, this time using Compact Discs. Coding located on the outside edge of the film enabled the discs to be perfectly synchronized with the film.
The latest upgrade is Dolby Atmos, which is a blanket term for processing sound in everything from your phone's headphones to high-end theatrical sound systems giving the listener more spatial awareness to the sound. In theaters this includes either ceiling mounted speakers or upward firing speakers that bounce sound off the ceiling to provide vertical positioning of movie sounds for a more immersive experience.
Many "home theater" sound systems are now available at modest cost which duplicate these formats in your living room. The first such systems were known as Dolby Pro-Logic, which is essentially the same as the original four-channel Dolby Stereo, modified slightly to accommodate the limitations of a home system. Dolby Stereo is encoded on most Hi-Fi stereo video tapes, so you can get great surround sound even with the old VHS tapes you may still have. Dolby Stereo, Dolby Digital, and DTS is encoded on most DVD and Blu-ray discs for use with the appropriate home systems. If your sound system doesn't have the full capabilities of the soundtrack, no worries. Surround formats are generally compatible with simpler sound systems (though we have had some challenges with Atmos Blu-. For example, if you have a disc with 5.1 channels of surround sound but you only have a simple two-channel stereo soundbar, you will still get the full range of sound but everything will be coming from the front.
Running time is for the original theatrical release. Some videos (sometimes called the “director's cut”) may contain added scenes that weren't shown in theaters, so some versions may have longer running times than those shown here. Some old movies may have had portions lost to film decay and may run somewhat shorter than the original.
MPAA/MPA ratings are determined by the Motion Picture Association of America which shortened its name in 2019 to the Motion Picture Association. They are intended as guidelines to help parents determine which movies are appropriate for children of various ages. MPAA/MPA ratings were first adopted in November 1968. Movies released prior to that date do not have such ratings. See www.filmratings.com for further information. Note: I am using the initials MPAA and MPA interchangeably in this guide. The shorter version is used only for movies released in 2019 or later.
