Five years after they teamed to produce Beauty and the Geek, Ashton Kutcher & Jason Goldberg’s Katalyst and JD Roth & Todd A. Nelson’s 3 Ball Prods./Eyeworks USA have combined forces for another social experiment-type unscripted series featuring unlikely pairs, Forever Young. TV Land announced this morning that it has given a six-episode order to the reality competition  based on an Eyeworks format, which teams septuagenarians with 20-somethings. “When separated by five decades, six wars and 10 presidents, Forever Young explores how revealing and how funny it can be when youth and wisdom join forces, whether in appreciation of the past, understanding the present or preparing for the future,” the producers said. Goldberg and Kutcher serve as executive producers for Katalyst;  Roth and Nelson for 3 Ball ; Eliot Goldberg and Marco Bresaz for TV Land.
