Two frames from the World Northal logo taken from the front of Rhino's Quadrophenia DVD. World Northal began as a competitor to outfits like New Yorker, disributing art films such as Cousin, Cousine and The Last Wave. When subsequent foreign films didn't perform well, World Northal moved into lucrative deals with exploitation distributors such as Raymond Chow's Golden Harvest and thereafter specialized mostly in martial arts titles. This burgeoning catalog morphed into the popular "Drive-In Movie" package of films sold to syndicated television throughout the 1980s. Chris Poggiali has written a fascinating and exhaustive article covering this entire history.
Warner Communications-era logo retained at the start of Superman: The Movie DVD released in 2006. I haven't seen this on any other Warner titles. Maybe it's black and white to correspond to the black and white opening of the film? Also, note that "A Warner Communications Company" does not appear on this logo.
