Except when Lantz died, Universal focused it as name recognition, while the studio focused their eggs in their basket with bigger animated franchises to milk, which were The Land Before Time, An American Tail and, especially later on and as of right now, Despicable Me and its Minions spinoff. Otherwise, Universal focuses way more on either Jurassic Park, Fast & Furious and more lower budget films from either comedies some produced by Judd Apatow or horrors some produced by Jason Blum, among other current IPs.
Ehh, most of the 70s movies from Disney were proven to be a joke after Walt died, especially when you compare head to head with other major movie blockbusters from the likes of Jaws, The Omen, The Godfather, Alien, Westworld, Rocky, Close Encounters, Apocalypse Now, Grease, Superman and especially Star Wars.
That said, the 70s and 80s did provide some underrated, more mature themed, gems like Escape from Witch Mountain, The Black Hole, The Watcher in the Woods, Something Wicked this Way Comes, Return to Oz and Tron, which led Disney to create the more mature brand studios, Touchstone and Hollywood.
But I still don't remember the title of the movie.
