'Onward' Teaser Trailer Kicks Off a Fantastical Quest (or Just a Really Strange Errand)

Ugh, unicorns! The first teaser trailer for "Onward," Pixar's upcoming movie, is set within a fantastical world where elves, centaurs, dragons, and unicorns are completely normal (and sometimes, kind of annoying).

"Onward" centers on two teen elf brothers (voiced by Chris Pratt and Tom Holland) who set out on an extraordinary quest in a van named Guinevere to discover if there is still a little magic left in the world.

Pratt voices boisterous older brother Barley Lightfoot, while Holland is the younger, gawky brother Ian. Julia Louis-Dreyfus plays their mom. Octavia Spencer also stars.

The two "Avengers: Endgame" stars relied on their pre-established bond to generate chemistry. "They are clearly friends,” writer/director Dan Scanlon told People. "They’ve worked together before and hung out together. It was fun to sit back and watch them make each other laugh.”

Scanlon previously made "Monsters University" and the teaser has a similar vibe — fantastical elements within an everyday, normal setting.

Pixar has made two sequels as its last two movies ("Toy Story 4" and "Incredibles 2"). "Onward" will be its first original since 2017's "Coco."

"Onward" opens in theaters March 6.
