Hey Arnold! type TV Show

Not long after Nickelodeon has dug into the nostalgia vault to launch the ’90s programming block The Splat, the network has announced a brand new entry for one of its most beloved series.

EW has confirmed that a Hey Arnold! television movie is in development at Nickelodeon, though there currently is no announced air date. As Variety first reported, the TV movie will explore some of the series’ unresolved plotlines, including just where exactly Arnold’s parents are. (Arnold lived with his grandparents Phil and Gertrude, in the series, who gave their grandson the coolest attic bedroom a kid could ask for.)

Hey Arnold! first ran on Nick for five seasons beginning in 1996, following the titular football head and his group of schoolmates, including best friend Gerald and Helga, Arnold’s bully who also harbors a longtime crush for him. The mystery of Arnold’s parents was one of the longer term threads in the series, most fully explored in the two-part episode “The Journal.” A feature film was also released in 2002.
