Spark: A Space Tail, written and directed by Aaron Woodley (with additional written material by Adam Rotstein, Robert Reece and Doug Hadders), has been a mystery to me. I didn’t know what to make of the film. It premiered nearly a year ago at the Toronto Animation Arts festival. There were no advance reviews, and only a nebulous plot synopsis. All I knew was that it was a Canadian-Korean production from ToonBox and Redrover, the same people who brought us The Nut Job.
