Presumably after spending an afternoon carefully following complex instructions, the main cast for Warner BrosThe Lego Ninjago Movie has been assembled, with the legendary Jackie Chan leading an all-star cast. Along with Chan, the pic will star Dave Franco, Justin Theroux, Fred Armisen, Abbi Jacobson, Olivia Munn, Kumail Nanjiani, Michael Peña and Zach Woods.

Based on the line of Lego construction sets, The Lego Ninjago Movie follows Lloyd, member of a group of young warriors and Lego master builders who, with their kung fu master Wu, must defend Ninjago City against the evil warlord Garmadon. Complicating matters is the fact that Garmadon happens to be Lloyd’s father. With mech fighting mech and father fighting son, the undisciplined team of modern-day ninjas will learn to check their egos and pull together to save the city.

Chan stars as Wu, Franco is playing Lloyd, and Theroux voices Garmadon. Rounding out the cast of characters are Munn as Lloyd’s mother, with Armisen, Jacobson, Nanjiani, Peña and Woods voicing the rest of Lloyd’s secret ninja team.

Set to hit theaters September 22, 2017, The Lego Ninjago Movie is directed by Charlie Bean in his feature debut. Tom & Bill Wheeler are rewriting the script originally penned by Hilary Winston & Bob Logan & Paul Fisher from a story by Kevin Hageman & Dan Hageman and Winston, Logan and Fisher. The Lego Movie team of Dan Lin, Phil Lord, Christopher Miller and Roy Lee are producing, with Jill Wilfert, Chris McKay, Seth Grahame-Smith, and Keith Malone executive producing. Warner Bros will distribute worldwide.
