- Awesome Music: In the original film - "Opening," "Discovering the Neighborhood" and "Ryce's Theme," also the usage of "Roll Over, Beethoven"
- Bizarro Episode: Despite the rather improbable things that Beethoven does throughout the series (particularly in the third film) the films remained a pretty realistic feel throughout. Not so much with Beethoven's Christmas Adventure, which features one of Santa's elves as a central character, a magic bag which can produce an infinite number of toys, and Beethoven talking to people after they eat magic candy which allows them to understand dogs.
- Fridge Brilliance: George initially believing Beethoven bit the vet makes sense when you consider Beethoven is a large, male, un-neutered and ill-behaved dog.
- Fridge Logic: The sequels establish that George had never bothered to get Beethoven fixed in the first movie, despite the dog's out-of-control behavior costing him tens of thousands of dollars.
- He Also Did: Charles Grodin is also well-known as a guest pundit on 60 Minutes.
- Hey, It's That Guy!: Floyd is played by Nice Guy Eddie.
- Retroactive Recognition: In the first movie, look out for a pre-Everybody Loves Raymond Patricia Heaton and a pre-The X-Files David Duchovny as a pair of con artists who try con George out of his air freshener business.
- In addition, in the second movie, a pre-That '70s Show Danny Masterson appears as Ryce's boyfriend. Ironically, Danny's younger brother, Christopher Masterson, later of Malcolm in the Middle fame, actually originally had a minor role in the film, but his scenes were deleted as the producers felt he looked too similar to Danny. (No one on set knew that they were brothers.)
- Stefanie Scott from Disney's A.N.T. Farm was the girl that the main star's son had a crush on in Big Break. She was nice unlike a few of her other roles.
- Also in the first movie, the bad guy's mooks are Oliver Platt and the oscar-nominated Stanley Tucci.
- Nightmare Fuel: The first movie has a brief shot, complete with ominous music, of what looks like a crematorium. The second movie may have some of this for kids, as one scene has Regina's Mook, Floyd, holding a puppy over a waterfall. He never drops it, though.
- Unacceptable Targets: The American Veterinary Association wrote a letter to the head of the MPAA (Jack Valenti) about the main villain of the first film being a veterinarian.
- What Do You Mean, It's for Kids?: Date Rape Averted ends up being played for a laugh just because the would-be rapist suffers damage to his house and falls in the water.
