The "Adventure Time" movie will be produced by a powerhouse team of Chris McKay and Roy Lee, according to the Deadline report. McKay was a producer on 2014's hit animated movie "The Lego Movie," and has signed on to direct the upcoming "The Lego Batman Movie." Lee was also a producer on "The Lego Movie" as well as the popular "How to Train your Dragon" movies.

While Warner Bros. is said to be heading up the movie's production, Cartoon Network and Pendleton Ward, the creator of the series, will also reportedly be involved. We don't yet know when "Adventure Time" will make its way to theaters, but with a production crew this good, the movie will likely be worth the wait no matter howI'll be attending, signing books, and being on panels at the free Baltimore Book Festival Friday September 28-Saturday September 29th.

They expect 50,000 people. I hope to see some friendly faces while I'm down there.
