The actors lending their voices to The Secret Life of Pets (2016) aren't exactly a secret. In fact, most of them are pretty identifiable by voice, including Louis C.K. as Jack Russell terrier Max, Kevin Hart as white rabbit Snowball, Jenny Slate as white Pomeranian Gidget, and Eric Stonestreet as sloppy stray dog Duke. The star-studded animated comedy centers on Max's peaceful existence as a domesticated pet being upended by the arrival of Duke as they subsequently become lost on the streets of New York City.
