While New Line’s National Lampoon’s Vacation reboot has been put on hold, the stars of the hit feature comedy franchise Chevy Chase and Beverly D’Angelo are reuniting for a TV comedy project, which has received a large penalty by ABC that qualifies as a production commitment. They again will play a married couple, this time raising grandchildren. The single-camera comedy, which is looking for a writer and has not been set up at a studio yet, is eyed for the 2015-16 development season. Based on an original idea by Aaron Kaplan, who executive produces through his Kapital Entertainment, the untitled single-camera comedy would star Chase and D’Angelo as spouses in their 60s who are finally enjoying their golden years. They have raised their daughter, who is grown and now lives on the other side of the country with her two kids — and that’s the way these selfish grandparents like it; now they only need to see their grandkids a couple of times a year. But, due to circumstances beyond their control, they now are forced to raise their grandchildren.
