The only way in which that rather horrid movie could be said to have been based on Heinlein's novel is the fact that some of the characters had the same names (except that, for instance, Dizzy was a male, and died in the first chapter - Rico and Jelly almost missed the return boat because they were making pickup on his body). Heck, a character named "Juan Rico", whose household spoke Tagalog, was played by Casper van Diem...
I understand that what actually happened there was that Verhoeven had an anti-war film he wanted to make with vague sci-fi trappings, and someone noticed similarities to Starship Troopers - so rather than ask the Heinlein estate if they minded (I rather imagine Virginia would have given the okay, because the similarities were so very tiny), agents for Verhoeven purchased the movie rights. Reportedly, after the movie came out, Virginia was so incensed that she revoked all other movie rights to her husband's works - which is disappointing, as rumor has it that Disney was working on an adaptation of The Star Beast.
Never saw the cartoon, but I would hope the writers actually took the trouble to read Heinlein's novel at some point...
