Hey, It's That Guy!: Happens In-Universe late in Homeward Bound when Johnathan and Karen go to a movie and see an aged Matt Damon playing The Mentor; this is a big shock to them since they were put on ice in 1994, when his career was just starting to take off.
No Export for You: The Russian publisher Eksmo has purchased the rights to distribute the Colonization and Homeward Bound books in Russian-speaking countries and then promptly sat on them, refusing to translate and publish the novels for "idealogical reasons" and making sure nobody else could. Apparently, they didn't like how the USSR was shown in Colonization, even though it was arguably shown better here than in the Worldwar books.
Screwed by the Network: Russian readers will never get to read the Colonization trilogy, as the Russian publishing house Eksmo purchased the rights to the trilogy and then put it under wraps, refusing to translate or publish the books for "ideological reasons". Mostly, they disliked the way the USSR and the Soviet people are portrayed in the trilogy, as well as depicting the fall of the USSR in the 60s. Given that it was the 90s (a turbulent time in Russia), it's possible that the novels would be translated and published had a publisher purchased the rights now.
