"Jean-Pierre handles direction in the traditional sense of the word, that is, the direction of the actors, etc., while I do the artistic direction. Beyond that, in the day-to-day workings of the shoot of preproduction, it's obviously much more of a mixture. We write together, film together, edit together. According to each of our specialties, sometimes we'll be drawn to what we do best. There's a real complicity between us.
The success of Delicatessen allowed them to return to their early project — a science fantasyfilm The City of Lost Children which they conceived in the early 1980s, but weren't able to produce due to the lack of funding. It was released in 1995 and entered the 1995 Cannes Film Festival. The friends were then suggested to direct the fourth Alien installment, Alien Resurrection, and while Jeunet agreed, Caro refused to work on a film over which he lacked creative control, although he was persuaded to spend three weeks in Hollywoodworking on costume and set design. This movie marked the end of their creative partnership.
During the next 10 years Caro contributed to various projects as an art director, character designer and actor, often collaborating with Jan Kounen on his films. In 2008 he released Dante 01, his first feature film as a solo director which went almost unnoticed. In 2009 he directed a 53-minute documentary Astroboy à Robolandbased on the Astro Boy franchise. He returned to directing only in 2018 with a 5-minute short Loop.
In 2011 he became one of the initiators of the joined French-Japanese 3D animated movie Windwalkers: Chronicle of the 34th Hordeworking as an art director and visual effects supervisor, with Kounen attached as a director. The movie was based on the top-selling French novel La Horde du Contrevent by Alain Damasioand received a budget of €18 million ($23.4 million), but after American distributors requested to "marvelise" the script which they found "indigestible and too complicated", Caro and Kounen left the project which was eventually frozen in 2015.
