The original film, directed by Genndy Tartakovsky featured the voice talents of Adam Sandler, Andy Samberg, Selena Gomez, Kevin James, Fran Drescher, Steve Buscemi, Molly Shannon, David Spade and Jon Lovitz, all of whom are likely (but not yet confirmed) to return. It was released on September 28, 2012 and has already pulled in more than $250 million at the international box office.
Genndy Tartakovsky will not return for the sequel as he's currently committed to bringing Popeye to the screen instead.
The September date puts Hotel Transylvania 2 up against 20th Century Fox and DreamWorks Animation's B.O.O.: Bureau of Otherwordly Operations.
