Each year, the Madrid Círculo de Bellas Artes extends special invitations to the Complutense students during its series of annual conferences featuring prominent philosophers, sociologists, and psychologists. Likewise, all of the faculties have been able to benefit greatly by lectures given by some of the most illustrious figures in recent history, of all fields, from singer-songwriter and Catalan activist Joan Manuel Serrat to historian Ernst Gombrich, from writer Umberto Eco to communist politician Santiago Carrillo. Alejandro Amenábar wrote his first film, Tesis, while still attending the Complutense University. All the on-campus scenes in the film were shot in the School of Communications, which Amenábar himself had attended, and the building itself serves as major device in the plot.
