This was a (rather redundantly-named) division of The Weinstein Company that was formed reportedly for projects of "mutual interest" between the Weinstein brothers. Only two films and one TV series were distributed through the label.
(January 16, 2015-August 24, 2017)
Logo: It's the same as the "TWC" variant of The Weinstein Company logo, but the spotlights are blue and "TWC" slides to the left to make way for "-DIMENSION".
Technique: Same as the Weinstein Company logo, with the text sliding.
Music/Sounds: Same as the Weinstein Company logo.
Availability: Only seen on the U.S. release of Paddington and Gold. A short version was seen on the TV version of The Mist.
Legacy: It's just the standard TWC logo, but in blue. Not much to see or say here.
