Castle Films

Background
Castle Films was a home-movie distributor founded in 1924 in California by former newsreel cameraman Eugene W. Castle (1897-1960). The company originally produced business and advertising films. By 1931, it had moved its principal office to New York City. In 1937, Castle branched out into 8mm and 16mm home movies, buying newsreel footage and old theatrical films for home use. Castle's first home movie was a newsreel of the Hindenburg explosion. That same year, Castle launched his "News Parade" series, a year-in-review newsreel; travelogues followed in 1938. Castle also released sports films, animal adventures, and "old time" movies. (source: Wikipedia)

1st Logo (1935-1937)
Visuals: There are two towers on both ends and a barbican in the center, each with battlements. Two dark gray walls connect the buildings and several film holes are seen on the bottom of each part of the castle. The company name in a bold, white font with a black shadow is placed over the castle whereas "A" and "PRODUCTION" in a wide format are above and underneath it.

Closing Visuals: On a moving background featuring various landmarks, "The End" in a fancy font and stacked format is seen above the same logo without "A" and "PRODUCTION".

Variant:
 * An early version of the closing logo features an outlined version of the normal logo. Plus, "PRESENTATION" replaces "PRODUCTION".
 * A later closing variant has the logo on a dark blocky patterned background. Shortly after, "The End" in a fancy, cursive font fades in and slightly darkens the logo.
 * A Terrytoons variant has the castle with very little detail outside of several of a few horizontal black blocks on the top of the towers acting as the castle's battlements. "PRESENTATION" is also present instead of "PRODUCTION", but unlike the early variant, the "P" is bigger than the rest of the letters.

Technique:
 * Most of the variants: none.
 * On-screen closing variant: traditional animation.
