Fans of the well-known animator Hayao Miyazaki rejoiced when he announced that he is "ending" his retirement. The animator will allegedly begin working on a full-length animated.

According to Kotaku, Hayao Miyazaki announced his retirement in 2013, and he recently ended it earlier this week, to the delight of fans. Toshio Suzuki, Miyazaki's producer, revealed that he is working on another full-length film.

Despite announcing his retirement, the animator still visited and worked at Studio Ghibli. After Miyazaki stepped away from "directing features," he started to study computer animation. He then created a CG short titled "Kemushi no Boro (Boro the Caterpillar)."

On Friday, Feb. 24, Suzuki announced in a pre-Oscars interview for "The Red Turtle" that Miyazaki is indeed developing a new film. A Kyodo report revealed that according to Suzuki, Miyazaki emerged from retirement and is "currently doing prep work."

Suzuki will produce the upcoming film, and he added, "Right now in Tokyo, he's putting all his effort into making it [the feature]." Miyazaki plans to release the movie "before the 2020 Tokyo Olympics."

While the title or the plot of Miyazaki's upcoming film still hasn't been revealed, speculations say that he could be working on a full-length film based on the "Boro the Caterpillar" CG short, per the A.V. Club. The CG short will be shown "at the Ghibli Museum in Tokyo this summer."

The animator has revealed that "Boro the Caterpillar" is about "a tiny, hairy caterpillar" who is apparently "so tiny" that "it may be easily squished between your fingers." Clips of the short film show the animated Boro crawling, and Miyazaki is also shown discussing the CG short.

The animator is also shown sketching, and the video also reveals some of the completed sketches depicting Boro, other characters, and storyboards for the CG short. The video also showed glimpses of Miyazaki's notebook, which seemed to contain some of his ideas for "Boro the Caterpillar." In 2014, the animator "received a lifetime achievement award Oscar."
