ThunderCats is an American animated television series that was produced by Rankin/Bass Productions (the same that created the SilverHawks, TigerSharks, and The Comic Strip) debuting in 1984, based on the characters created by Tobin "Ted" Wolf. The series follows the adventures of a group of cat-like humanoid aliens. The animation was provided by Pacific Animation Corporation. Season 1 of the show aired in 1985 (65 episodes), followed by a TV movie entitled ThunderCats - HO! in 1986. Seasons 2, 3, and 4 followed a new format of twenty episodes each, starting with a five-part story.
The series was originally distributed by Rankin-Bass Productions' then-parent company Telepictures Corporation, which would later merge with Lorimar Productions in 1986. In 1989, Lorimar-Telepictures was purchased by and folded into Warner Bros., whose television syndication arm would eventually assume distribution of the show; Warner Bros. have had the rights to the series (and all Lorimar-Telepictures programming) from that point on.
There were also several comic book series produced: Marvel Comics' version (currently owned by Warner Bros. rival Disney), 1984 to 1988; and five series by Wildstorm, an imprint of DC Comics (Warner Bros.' corporate sibling), beginning in 2003. Items of clothing featuring the ThunderCats logo and DVD boxsets of the original series have enjoyed a resurgence in recent years as nostalgia for the former children's favorite has grown.
It was announced on June 5, 2007, that Aurelio Jaro is making a CGI-animated feature film of ThunderCats, based on a script written by Paul Sopocy. In October 2007, Variety magazine revealed that Jerry O'Flaherty, veteran video game art director, had signed on to direct. The film is being produced by Spring Creek Productions. It was originally set for a summer 2010 release, but it has since been reported that the movie is on hold. Concept art for the film has also been leaked online.
In June 2010, a press release revealed that a new animated series by Warner Bros. Animation was in production for Cartoon Network with animation provided by Studio 4°C
