Fred MacMurray was sitting in Walt Disney’s office in 1958 when Disney pitched him the wildest idea – play a man who turns into a dog, then keep playing dog-related roles for the next decade to create Hollywood’s first connected movie universe.

Shaggy Origins
Disney cinematic universe technically started with The Shaggy Dog releasing March 19, 1959. The fantasy comedy about a teenager cursed to transform into a sheepdog became Disney’s highest-grossing film to that point, earning $9.6 million against a $1 million budget.
But here’s what most film historians miss – Disney deliberately planned sequels and spin-offs before the first film even opened. Internal memos from 1958 show Disney executives mapping out five potential dog-related comedies featuring MacMurray, creating Hollywood’s first franchise blueprint.
The studio released The Shaggy D.A. in 1976 with Dean Jones (who appeared in the original as a supporting character) taking over the lead. Then came The Return of the Shaggy Dog TV movie in 1987, followed by a 1994 TV series, and eventually the 2006 Tim Allen remake.
Franchise Blueprint
What made the Disney cinematic universe innovative wasn’t just making sequels – studios had done that since the silent era. Disney’s genius was creating interconnected stories where supporting characters from one film became leads in others, establishing shared mythology across multiple projects.
The Absent-Minded Professor (1961) starred MacMurray as a scientist who invents flying rubber. Characters from The Shaggy Dog appear in background scenes, and the film references events from the earlier movie. This represented the first time a studio deliberately connected non-sequel films into a larger world.

Disney continued this approach with the Dexter Riley trilogy (The Computer Wore Tennis Shoes, Now You See Him, Now You Don’t, The Strongest Man in the World) which featured recurring characters and locations from previous films. Medfield College became Disney’s answer to what Marvel would later do with the MCU.
Unrecognized Innovation
The Disney cinematic universe of the 1960s-70s influenced everything from James Bond to Star Wars, yet rarely receives credit for pioneering shared universe storytelling. Disney proved audiences would follow characters across multiple films if given proper reason to care.
Walt Disney himself obsessed over continuity between films. He created detailed character backstories that never appeared on screen but informed how actors approached their roles. Kurt Russell, who starred in several Disney universe films, said Disney kept extensive files tracking every character’s history across projects.
The financial success validated Disney’s approach. Between 1959-1976, the interconnected comedy films earned over $180 million combined – equivalent to $1.2 billion today. This profitability encouraged other studios to attempt similar strategies, though none succeeded as consistently.
Modern Parallels
The Disney cinematic universe pioneered techniques Marvel perfected decades later. Post-credit scenes? Disney used those in The Love Bug (1968) to tease Herbie Rides Again. Crossover events? The Barefoot Executive (1971) featured characters from three previous films teaming up.
Today’s superhero universes owe massive debt to Disney’s 1960s experiments. Kevin Feige studied these films when planning the MCU, specifically noting how Disney balanced standalone stories with larger universe building.

The Disney cinematic universe proves that intellectual property franchising isn’t a modern invention – it’s been part of Hollywood for 65+ years. Disney just did it first, better, and with talking dogs instead of superheroes.
