Action League Now! (advertised as Action League Now!: The Series when packaged into a half-hour block) is a series of stop motion shorts that aired as part of both All That and KaBlam! on Nickelodeon. It was made using "chuckimation", a combination of stop-frame animation and live-action shots where things are simply thrown ("chucked") or dropped into frame to simulate movement, and wiggled around to simulate talking. The series follows the adventures of a superhero league, composed of various action figures, toys, and dolls. The show was created by Robert Mittenthal, Will McRobb, and Albie Hecht.

Most episodes took place in a house of an unseen resident. Many of the characters were voiced by radio personalities from Pittsburgh.

From 1998 to February 10, 2002, Nickelodeon briefly ran Action League Now! shorts on their own, combined to fill a half-hour timeslot. These standalone edits are available on Paramount+.
