I don't think that Playmobil releases most sets with movies in mind. However, if there are popular movies in that genre, then the theme is likely to sell well. The Roman theme had "Gladiator". Even if it's not a kids' movie, I guarantee some children saw it, and those who didn't probably thought it must be cool because their parents watched it but wouldn't let them.
And there is plenty of reasonably realistic anime out there, though I think a lot of it is geared towards girls more than boys. A lot of boy anime have fantasy elements, while many girl anime are more focused on romance.
