After completing "Allures" in 1961, Jordan Belson gained high artistic recognition, yet due to the lack of commercial prospects for experimental animation, financial constraints, and the challenging industry environment, he became thoroughly disillusioned with filmmaking and chose to stop creating, entering a period of silence in his career. Later, he received funding from the Ford Foundation, allowing him to return to the studio and resume his creative work. The 1964 film "Re-entry" became a landmark work following his comeback. The title not only symbolizes a spacecraft re-entering the atmosphere but also metaphorically represents the return of his artistic life and a spiritual rebirth. It marks a key turning point in his transition from abstract light and sound to cosmic meditative imagery.
