In case you couldn’t tell, this is a Danish film. It was also a major success that it received two sequels (the second of which being CG) and a tv series. There is an English version of this movie called Go Hugo Go, but it’s done by Miramax.
That is, unless that’s the version you want to show.
It was suggested in one of the first posts of this thread, but I’d also like to suggest Chuck E. Cheese and the Galaxy 5000.
It’s got songs, obvious greenscreening, an interspecies romance that tops Hugo’s fox/cartoon thing in absurdity, and Christopher Sabat as Munch, the purple guy. That’s right, Funimation actually worked on this.
If you need a sample, it’s on Everything is Terrible. And here’s the full video on YouTube.
