The final trailer for The Cat in the Hat is now online (more than an entire year after its first teaser was released), and you can check it out in the player above. Be warned the preview might be filled with potential spoilers as this seems to be a cliff notes version of the plot. In addition, Warner Bros. has quietly released a full theme song for the titular character on YouTube. It’s very catchy. You can hear it for yourself here.

Meet the Cat in the Hat you don’t know! In the wonderfully whimsical tradition of Dr. Seuss, The Cat in the Hat comes to the big screen in his animated theatrical feature film debut, an all-new, epic adventure with an edge, where mischief, magic and mayhem reign supreme. Doing what he does best, the Cat—voiced by Bill Hader—spreads joy to kids in his hilarious, signature and singularly irreverent way, transporting them and audiences on a fantastical journey through a world they’ve never seen before.

In the film, our hero takes on his toughest assignment yet for the I.I.I.I. (Institute for the Institution of Imagination and Inspiration, LLC): to cheer Gabby and Sebastian, a pair of siblings struggling with their move to a new town. Known for taking things too far, this could be this agent of chaos’s last chance to prove himself…or lose his magical hat! Starring alongside Hader are Xochitl Gomez, Matt Berry, Quinta Brunson, and Paula Pell, and featuring Tiago Martinez, Giancarlo Esposito, America Ferrera, Bowen Yang, and Tituss Burgess.
