After a September that has given us the most entertaining mafia series and in which the Emmys have presented us with assignments, October arrives with our favorite platforms scheduling some of the most anticipated autumn premieres. Such as the new seasons of La Diplomática and Lupin, the Matthew Perry docuseries, and the adaptation of the Nobel Prize-winning novel East of Eden.

The Spanish audiovisual industry will also premiere several novelties in the coming weeks, from the Raphael biopic, titled Aquel, to the adaptation of Mabel Lozano’s book El proxeneta, and to the detective mystery based on the Domingo Villar novel Caldas. El último barco. Fiction for all tastes, complemented by a Marvel character, a formidable serial killer, and an audiovisual classic that becomes a series half a century after hitting the cinema screens.

October’s series premieres are numerous, but we have selected ten that everyone will be talking about, so you stay up to date with what is cooking on streaming platforms.

A story about good and evil and the influence that family legacy has on the present of each individual, with Florence Pugh playing the role of Cathy Ames, a part that fits her like a glove.
