While there is knowledge about the presence of political themes in Alki Zei’s (1925–2020) children’s and youth literature, there is scant research on how class issues are represented in her work and how they are adapted to other media forms. This chapter, using a case study design and a social-semiotic-inspired text analysis, offers a closer look at the Greek produced television-series adaptation of Wildcat under Glass (ERT, 1990), which was mostly recently broadcast in Greece in 2012 and is now available on the online streaming platform ERT Flix. Drawing on a materialist and “culturalist” understanding of class as well as on the concept of comparative criticism, they focus, in particular, on how class issues are represented and (re)adapted to television, the entertainment genre, and a wider audience. Contrary to initial assumptions, the authors show that class issues remain, in principle, unaltered and discuss a number of possible explanations.
