Background: Commonwealth United Entertainment was the movie production/distribution company, formerly know as also Television Enterprises Corporation. It was purchased by National Telefilm Associates, Inc. (known now as "CBS Television Distribution") in the late 60s.
1st Logo[]
(1968-1969)
Logo: On a black background, we see a series of rings (in red, green, and blue) zoom in. A white ring comes in and the right side opens and reveals "UC", while still in the original "C". Underneath, "COMMONWEALTH UNITED CORPORATION" comes out from the center and the text forms on either side after moving from the center. The logo looks similar to the 1968 Cinerama Releasing Corporation logo.
Variant: Depending on the film quality, the red ring would appear reddish-orange, the green ring yellow, and the blue ring green. Technique: The rings zooming in.
Music/Sounds: A dreamy fanfare, which was actually "Climb to Altitude" by Trevor Duncan.
Availability: Very rare. Can likely be seen on any of the studio's output from this time frame. May get preserved on home media releases by NTA Home Entertainment/Republic Pictures Home Video, Artisan Entertainment/Lionsgate Home Entertainment, and/or Olive Films.
Legacy: For a 1960s logo, this logo looks pretty advanced and looks more like a Scanimated logo from the late '70s.
2nd Logo[]
(1969-1971)
Nickname: "The Commonwealth Displayer"
Logo: On a black background, we see white spots (as it were a football display) appearing on determined places on the screen, then, silhouettes of all continents in the world appears, made of color spots also. Once all the continents have appeared, a blue background (made of spots) wipes from the left. Once completed, all screen turns blue. The letters "COMMONWEALTH UNITED" (in brown, and made with spots too) appears. After a few seconds, the lettering turns light pink, and the background turns darker. Then, the background turns black, and the letters change to yellow, and at the end, to white.
FX/SFX: The spots appearing, and the wiping.
Music/Sounds: Several "ding" like sounds when the white spots appears, then a funky brass melody is heard, accompanied with bass and piano.
Availability: Rare. Can be seen on some of their output released by NTA Home Video and Republic Home Video. Most recently seen on the Blue Underground DVD release of Venus in Furs as well as the Lionsgate DVD and Olive Films Blu-ray releases of Julius Caesar (1970).
