Advertised Extra: Gurin, in Gurin med Reverompa. Though the story is really about him, he doesn't get a lot of screen-time; more than half the movie is dedicated to the madcap adventures of Solan and Ludvig as they try to find him, and Gurin himself is only in the movie for about 20 minutes altogether... less than a third of the movie's runtime. Narrative Profanity Filter: A variant in The Snow Machine. When Reodor turns hinself invisible, the narrator steps in to tell the audience that the reason we're not hearing the many inventive swearwords Reodor is currently using, is that he's turned inaudible as well as invisible.

Author Avatar: Kjell Aukrust once described both Solan and Ludvig as this, claiming that "Solan is me before I turned fifty — Ludvig is me after I turned fifty." Disney Acid Sequence: In Gurin, Ludvig is entranced by the beautiful music played at the restaurant and lapses into a floaty dream sequence. Counts as a bit of a Big-Lipped Alligator Moment. When I saw the first two films I was pleasently suppriesed and liked them a lot. I didn't think neither Solan og Ludvig - Jul i Flåklypa (English title: Louis & Luca and the Snow Machine) which is the first film, or Solan og Ludvig: Herfra til Flåklypa (Louis & Luca: The Big Cheese Race), the second film, came close to Flåklypa Grand Prix quality. But I thought they were good animation films and quite entertaining. Adaptational Villainy: Rudolf Blodstrupmoen, while never a particularly nice person, wasn't a bad guy in Aukrust's original writings. In the movie he's much more ruthless and more willing to do whatever it takes to win, which includes stealing, cheating and sabotage.

Side guide

Big Damn Heroes: Ludvig in The Snow Machine, who saves Reodor and Solan when they're in danger and ultimately ends up being the one to resolve the main plot. Pinchcliffe Grand Prix or Flåklypa Grand Prix is a 1975 Norwegian animated feature film, directed by Ivo Caprino based on the works of author Kjell Aukrust, and featuring characters from many of Aukrust's books. Reodor Felgen's prototype of a spacecraft is struggling with some flaws but by the good financial support of the state, represented by bureaucrat Vigfus Skonken, the funding is secured for this ruthless space adventure. The project does not make Ludvig less nervous. Even Solan have some doubt that the spaceship can fly to the moon. They also get moral support from Mayor, Countess Stengelføhn-Glad. The character Stengelføhn-Glad is probably the only thing I didn't like about this film. I thought she was an annoying new character. And I have to talk a little bit about the humour in the film. I find in many animation movies they exaggerate the humour and make situations with characters just for laughs. But here I found the situations to make sense. They were both funny and they make sense for me. Parodied with Solan in Gurin, when he spends the climax of the story off-screen, and barges in to announce that he's here to save the day and has everything under control... after the problems are over and the plot has been resolved.

Arab Oil Sheikh: Sheikh Ben Redic Fy Fazan. Translates something like Sheikh Ben Radish Gosh Tarnit. Break the Haughty: Gurin tries to invoke this, with the titular character being a prankster and Gadfly who after growing a fox tail gets to be on the receiving end of teasings and pranks. Solan and Ludvig would go on to star in many books by Aukrust, usually composed of small humorous Slice of Life vignettes, and the pair would return to the movie world in the hand-drawn animated movie Solan, Ludvig og Gurin med Reverompa ("Solan, Ludvig and Gurin with the Fox Tail") in 1998, in which Reodor had a minor role. In this story, Solan is an Oslo private detective, with Ludvig as his assistant, and they are tasked with finding a nisse (sort of a Norwegian gnome) named Gurin, who has grown a fox's tail.

The follow-up movies provide examples of the following tropes:

All Drummers Are Animals: As a literal example, Emanuel Desperados, aside from being a gorilla driver, also guest stars in a human band at the unveiling of Il Tempo Gigante, naturally as a drummer. Dub Name Change: Since the Norwegian names are often difficult to pronounce for anyone who isn't Norwegian (and a lot of the names are pun-based anyway), the various language dubs often change the names of the characters. The English names for the main characters are: In Mission to the Moon it's the bureaucrat Vigfus Skonken, who helps out on the moon journey but has his own less than idealistic reasons for doing so.

Good Smoking, Evil Smoking: Solan smokes a cigar in some of the scenes in Gurin, including the opening scene. He seems to be doing it mostly to come across as a Cultured Badass, but his success varies. Adaptation Expansion: Gurin med Reverompa was based on a shory story by Aukrust, but since this stories was... well, short, they had to expand them with a lot of extra materials and plotlines, as well as make Solan and Ludvig active participants in the story (the original short story just had Solan tell Ludvig the story of Gurin).One day, the trio discovers that one of Reodor's former assistants, Rudolf Blodstrupmoen ("Rudolph Gore-Slimey"), has stolen his design for a race car engine and has become a world champion Formula One driver. Solan secures funding from an Arab oil sheik who happens to be vacationing in Flåklypa, and to enter the race, the trio builds a gigantic racing car: "Il Tempo Gigante". Invisibility: Reodor accidentally turns himself invisible in The Snow Machine. Uniquely, being invisible also renders him unable to talk, so he can't tell Solan and Ludvig what happened to him (trying to communicate through written notes just makes them think there is a ghost around when they see notepads and pencils fly by themselves.) Later in the movie, Solan's beak is accidentally turned invisible, which means he can't talk either. Breakout Character: Ludvig, the only character in the movie who hadn't appeared previously in Kjell Aukrust's books (outside a single illustration), emerged as the star of the movie and went on to become Aukrust's most beloved character, starring in many books alongside Solan (who until now had been a solo character). Adaptational Villainy: Just like in the first movie, both the follow-up movie takes an established Aukrust character and puts them in an antagonistic role. Some of them do end up with a Heel–Face Turn, though. Burning Rubber: Il Tempo Gigante is a fast and powerful car, to the degree that the asphalt itself gets roasted and curls off the ground when it takes off.
