Rebecca Rubin Film and Media Reporter Kumail Nanjiani and Elizabeth Banks will lead the voice cast of Universal and Illumination’s upcoming “Migration,” an animated adventure about a family of ducks on the go. “I find ducks so irresistible,” Illumination founder Chris Meledandri told the crowd at CinemaCon on Wednesday as he unveiled the compete voice cast for the original cartooned comedy. “In our movie, ducks worked beautifully to convey the relatable quirks and truths of a modern-day family.” Attendees of the annual Las Vegas-bassed exhibition industry trade show were also treated to an extended first-look at “Migration,” which opens in theaters on Dec. 22. The road-trip story follows a family of ducks, who try to convince their overprotective father to embark on the vacation of a lifetime.
