The film production company was created after the enacting of the Spanish Law 22/1999 regulating the collaboration between the television operators and the film industry.

[1] The studio of the Grupo Antena 3 (later Atresmedia) was created in 2000 under the brand identity 'Ensueño Films'.

[4] In light of the ensuing forced investment of the television operators in film production, Atresmedia (through its own studio) as well as rival operator Mediaset España (through its respective producing arm Telecinco Cinema) eventually became the two main film producers in the country.

[5] In 2019, Atresmedia Cine was integrated within Atresmedia Studios, the division created in 2017 to produce fiction for third-party platforms,[6] and which was in turn integrated in 2020 into a newly created joint-venture of Atresmedia with Telefónica, Buendía Estudios [es].

[7] In 2022, Jaime Ortiz de Artiñano was appointed as the new Director-General of Atresmedia Cine, replacing Mercedes Gamero, who quit the position after 18 years working for Atresmedia to join Beta Fiction Spain.
