Stay Tooned! (1990-1995)
This was an ambitious and expensive series for the time as it mixed cartoon animation and real live action like you saw in movies such as "Who Framed Roger Rabbit" and "Space Jam"
The first episode starts with a group of evil cartoon characters in their a cartoon universe, finding a way of opening up a portal to our real world. They come through the portal and kidnap a group of cartoon animators and artists, and bring them back to their cartoon universe, for nefarious purposes.
While they are being held captive, a group of good cartoon characters come to our real world and team up with a group of real people, to try and release the captive artists back to our real world, stop the evil characters and close the portal so this cannot happen ever again.
Due to how ambitious and expensive this was for a TV show at the time, mixing real world live action and animation and the length of time each episode took to make and edit, only 8 episodes were made, each lasting just over an hour with the first released in 1990, then one in 1991, two released in 1992, one in 1993, one in 1994, and the two part finale in 1995. The reason for the delay in releasing episodes was due to the editing process taking more time than anticipated and a few scenes having to be reshot and reanimated here and there, delaying the release of some episodes.
Each episode would be a continuation of the last, almost like a movie series on the small screen.
A VHS collection was released after the final episodes aired, then years later a DVD special with commentary and behind the scenes look at how the series was made. Years after that, the show was remastered and released on Blu-Ray.
