Lani Pixels has announced that Mel Brooks (The Producers), Christopher Lloyd (Back to the Future), Jacob Tremblay (Wonder) and Kenan Thompson (Saturday Night Live) have signed on to lend their voices to an as-yet-untitled animated feature, which marks the directorial debut of Kim Pagel.

Variety reports that the project “follows a brother and sister as they attempt to rescue their grandfather from supernatural forces that have invaded his isolated island. Guided by a charming Irish rogue, the siblings end up on a dangerous journey filled with magic and mystery.”

“It is an honor to be working with such a talented and dynamic cast on this project,” said Kim Pagel. “While this has been a passion project for many years, the themes of family unity and courage in the face of adversity are particularly important these days.”

“When we founded Lani Pixels it was our dream to tell exceptional stories and produce feature films that resonate with an international audience,” added Thomas Pagel, Lani Pixels co-founder. “Thanks to our production team, that dream is becoming a reality. While this project is the culmination of years of hard work, it is really just the beginning.”

Production and additional casting on the movie are now underway.
