See Channing Tatum, Gina Rodriguez, and Zendaya pose with their Smallfoot characters in new portraits

Channing Tatum, Gina Rodriguez, Common, James Corden, Yara Shahidi, Zendaya, Ely Henry, Jimmy Tatro, and LeBron James star in the upcoming animated film Smallfoot — in which one Yeti sets out to discover whether humans really exist.

The animated movie opens Sept. 28.

Tatum plays Migo, an honest and true young Yeti with a big heart. Migo has always trusted the village teachings, such as: do what you’re told and don’t ask questions. But when he accidentally discovers something he was told doesn’t exist – a Smallfoot – he wants everyone to know about it. Even if it turns their lives upside down.

Rodriguez brings to life Kolka, the science enthusiast whose favorite subject is the elusive Smallfoot. As she studies artifacts she’s collected over the years — a jacket, toilet paper, a boot — she hopes to figure out what the objects are for.

Common plays the Stonekeeper, who watches over the ancient stones on which the history and rules of the village are written. With his big curved horns, long white beard and imposing presence, the Stonekeeper is the most powerful Yeti in the village and no one dares to question him…except for Migo.

Corden plays Percy — a Smallfoot — who comes face to face with Migo. When he realizes Yeti exist, he sets out to record the encounter with the support of his producer Brenda (Shahidi).

Zendaya plays Meechee, the Stonekeeper’s daughter, who believes there’s more to the world than her Yeti community.

James plays Gwangi, a lover of conspiracy theories who believes in the existence of Smallfoot. Convinced there are secrets everywhere, Gwangi is determined to find out the truth about his Yeti village and Smallfoot.
