Nicktoons Cinematic Series

The Nickelodeon Cinematic Animated Universe (NCAU; alternatively called the Nicktoons Cinematic Universe) is an American animated media franchise that is centered on a series of computer-animated films based on the Nicktoons television series by Nickelodeon, produced by Nickelodeon Movies and distributed by Paramount Pictures. The franchise starts out with its first film Danny Phantom Returns and ending with its last film Doug.

Animation
Rather than going with the traditionally hand-drawn animation from the shows, the NCAU relies on various computer-animation companies for its films such as Bardel Entertainment; Reel FX Creative Studios; Mikros Image; Blur Studio; Marza Animation Planet; and Rainmaker Studios.

Films
The film series has a variety of Nickelodeon's old Nicktoons series from the 1990s to the mid-2000s. However, its exceptions are SpongeBob SquarePants; Rugrats; Hey Arnold!; and The Wild Thornberrys, due to already receiving their own films (even if Doug already had its own film which was produced during its Disney era, The Fairly OddParents already had a bunch of TV films and Invader Zim has its own film on Netflix); and Ren and Stimpy and Rocko's Modern Life, due to being considered as more of adult animated shows.

The films of the NCAU were not allowed to have sequels, while its exceptions were Barnyard Moo and Jimmy Neutron 2.0, as their predecessors have never been in the NCAU to begin with.

Music
The films have their scores composed by well-known composers such as Brian Tyler, Hans Zimmer, Mychael and Jeff Danna, Michael Giacchino, John Debney, and Tyler Bates; while a composer to a Nicktoons series is a music supervisor.

Theme park attractions
After the release of Teenage Robot Reborn, a theme-park ride based on the film is made after production of the film finished. Entitled Teenage Robot: Escape From Contraxis, the ride depicts the film's character Garr bringing theme park attendees to Contraxis to rescue his Jenny, Brad, Tuck and Sheldon from the Contraxians. The ride has no connection to the film, nor is it a follow-up.
