Another view of the evolution of Resnais's career saw him moving progressively away from a realistic treatment of 'big' subjects and overtly political themes towards films that are increasingly personal and playful. Resnais himself offered an explanation of this shift in terms of challenging what was the norm in film-making at the time: having made his early films when escapist cinema was predominant, he progressively felt the need to move away from exploration of social and political issues as that itself became almost the norm in contemporary cinema. Experimentation with narrative forms and genre conventions instead became a central focus of his films.
