If you grew up on Rankin/Bass stop-motion specials, you probably remember the cozy vibes of the original Rudolph or the hand-drawn magic of Frosty the Snowman. But then there is the 1979 feature-length crossover. It’s a trip. When people look up the cast of Rudolph and Frosty's Christmas in July, they usually expect a quick list of names from the 60s. What they find instead is a bizarrely deep roster of Old Hollywood icons, Broadway legends, and a plot involving a wizard named Winterbolt who owns bloodthirsty ice dragons. It's a lot.
Honestly, this movie is the Avengers: Endgame of the Rankin/Bass universe, except way more psychedelic and featuring much more accordion music. It brought together the two biggest icons of the holiday season and threw them into a seaside circus setting. Why? Because the late 70s were a wild time for animation.
The Voice Legends Who Made It Happen
The most important thing to know about the cast of Rudolph and Frosty's Christmas in July is that it served as a final bow for some of the most distinctive voices in animation history. Billie Mae Richards returned as Rudolph. She had been voicing the red-nosed reindeer since 1964, and by 1979, she had the character’s nasal, optimistic vulnerability down to a science. It’s actually kind of impressive how she kept that youthful "fawn" energy for fifteen years.
Then you have Jackie Vernon. He’s the definitive Frosty. His breathy, slightly confused delivery is what makes Frosty feel like a giant, lovable toddler. In this movie, he has to play a version of Frosty who is genuinely terrified of melting—not just from the sun, but from a magical curse. Vernon’s performance is weirdly grounded for a movie about a talking snowman at the beach.
Mickey Rooney as the Big Guy
We have to talk about Mickey Rooney. He didn't just play Santa Claus; he was the Rankin/Bass Santa. He voiced the character in Santa Claus Is Comin' to Town and The Year Without a Santa Claus. By the time he joined this specific cast, his Santa was less of a jolly caricature and more of a tired, paternal figure trying to keep the peace between magical creatures and a greedy circus owner. Rooney’s energy is the glue that holds the chaotic plot together.
Red Buttons and the Comedy Relief
Red Buttons plays Milton, the ice cream man who flies a hot air balloon. If that sounds ridiculous, it’s because it is. Buttons was an Academy Award winner (for Sayonara), and his presence in the cast of Rudolph and Frosty's Christmas in July highlights how these specials attracted legitimate star power. He brings a vaudeville timing to the role that feels very "old school" entertainment.
Ethel Merman: The Secret Weapon
You can’t discuss this cast without mentioning the Queen of Broadway. Ethel Merman voices Lilly Loraine, the owner of the circus. Think about that for a second. You have the loudest, most powerful voice in theater history playing a stop-motion puppet. When she sings, she isn't holding back. It’s spectacular.

Lilly Loraine isn't your typical villain. She’s a tough-as-nails businesswoman who actually cares about her performers. Merman gives the character a rasp and a grit that you just don't see in modern children's programming. It’s a "working-class" performance in a movie about magic reindeer.
The Villain: Paul Frees as Winterbolt
If you don't know the name Paul Frees, you definitely know his voice. He was the Ghost Host at Disney’s Haunted Mansion and the voice of Boris Badenov. In this 1979 special, he plays the antagonist, Winterbolt.
Winterbolt is a terrifying addition to the lore. Unlike the Abominable Snow Monster, who was just a misunderstood beast, Winterbolt is a calculated sorcerer. Frees plays him with a Shakespearean weight. He makes you believe that the stakes are real, even when the plot involves a magic "Lady Boreal" (voiced by Nellie Bellflower) and a "Clock of Winter." Frees’ range is the reason the cast of Rudolph and Frosty's Christmas in July feels so much more mature than the 1964 original.
Why the Casting Choices Mattered
Rankin/Bass had a formula. They loved "Animagic" stop-motion, and they loved casting stars who were slightly past their prime but still had immense talent. This created a specific "theatrical" feel. It wasn't just "cartoon voices." These were actors who understood how to project.
Take Shelley Winters, for example. She voices Crystal, Frosty’s wife. Winters was a powerhouse actress known for The Poseidon Adventure. Hearing her play a gentle, supportive snow-woman is a bit of a trip, but she brings a warmth to the role that makes the relationship between Frosty and Crystal feel surprisingly sweet.
The Musical Element
Because this cast included Merman and Rooney, the music had to be big. Johnny Marks, the man who wrote the original "Rudolph" song, returned for the soundtrack. The cast had to handle complex lyrical numbers that moved the plot forward. It wasn’t just about singing "Happy Birthday" anymore; they were singing about the legalities of circus ownership and the ancient laws of winter magic.

Addressing the "July" Misconception
A lot of people think this was just a TV episode. It wasn't. It was a theatrical release in some territories and a massive TV event in others. The runtime is nearly 100 minutes. That’s a long time for stop-motion. The cast of Rudolph and Frosty's Christmas in July had to sustain an actual narrative arc.
The "July" setting allowed the animators to put these characters in environments we’d never seen. Rudolph on a boat. Frosty under a magical spell that keeps him from melting. It gave the voice actors room to play with different emotions—mostly anxiety and desperation, which is a weird vibe for a Christmas movie, but it works.
The Legacy of the 1979 Special
Is it the best Rankin/Bass special? Probably not. That title usually goes to the 1964 original or The Year Without a Santa Claus. But is it the most ambitious? Absolutely.
The sheer density of the cast of Rudolph and Frosty's Christmas in July is proof of that. You don't hire Ethel Merman and Mickey Rooney unless you're trying to make a statement. It was an era where these holiday specials were the biggest events on the television calendar. Families would gather, and the networks would pour money into these productions.
The movie deals with some surprisingly dark themes. It tackles the idea of Rudolph losing his nose's glow because of a lie, and the concept of magical extinction. The voice cast had to sell those moments. If Billie Mae Richards hadn't been so convincing as a heartbroken Rudolph, the whole thing would have fallen apart.
The Weirdness Factor
Let’s be real. It’s a movie where a reindeer and a snowman help a circus stay in business while fighting a wizard with a scepter. It’s weird. But the cast took it seriously. There is no "winking at the camera" or ironic detachment. They played it straight, and that is why it has such a cult following today.

Practical Takeaways for Fans and Collectors
If you're diving back into this classic or introducing it to a new generation, keep these things in mind about the production:
- Look for the Uncut Version: Many broadcast versions of this movie are heavily edited for time. To truly appreciate the work of the cast of Rudolph and Frosty's Christmas in July, you need to see the full theatrical cut, which includes more of Merman's musical numbers.
- Appreciate the Voice Overlap: Notice how Paul Frees voices multiple characters. This was a hallmark of the era. He wasn't just the villain; he was a master of utility.
- Check the Credits: Beyond the big names, the "additional voices" include stalwarts of the 70s voice acting scene, like Don Messick (the voice of Scooby-Doo), who played many of the secondary creatures.
- Sound Quality: Because this was recorded in the late 70s, the audio fidelity is a huge step up from the 1964 special. You can hear the nuances in Rooney’s grit and Merman’s vibrato much more clearly.
The film stands as a monument to a specific type of Hollywood crossover. It’s the moment where the "Golden Age" of theater and the "Silver Age" of animation collided. It might be messy, and it’s definitely long, but the performances are undeniable.
If you find yourself watching it this year, pay attention to the dialogue. It’s snappier than you remember. The voice actors weren't just reading lines; they were building a world that felt much larger than a North Pole workshop. It’s a world of contracts, circus tents, and ancient magic—and it only works because the people behind the microphones were some of the best to ever do it.
To truly experience the impact of this era, watch it back-to-back with the 1964 Rudolph. You’ll hear the evolution of Billie Mae Richards' voice. You'll hear how the character of Santa evolved from a slightly grumpy boss to a grandfatherly figure. It’s a masterclass in character consistency over decades.
Grab a physical copy if you can. Streaming services often have compressed audio that loses the depth of the orchestral score and the subtle character work of the cast. In a world of CGI, these hand-crafted performances feel more human than ever.
