Lucasfilm has released a new teaser for its upcoming film Solo: A Star Wars Story, showing off a bit more of Han Solo’s early days and his friendship with Chewbacca.

We’ve already seen a couple of trailers for the film, which show off a bit of the criminal underworld of the universe, as well as the film’s Wild West vibe. This new teaser is short, but it shows off a bit more of the film’s titular hero, Han Solo. There’s a bit more of the train heist that we’ve seen in the other trailers and quite a bit more of Han and Chewie’s interactions — including when Han first learns Chewie’s name.

This certainly sets up a film that helps establish the character’s relationship in the new Star Wars canon. In the now-de-canonized expanded universe, Han had saved Chewie from Imperial slavery — and was promptly booted from the Empire as a result. This new teaser shows off a bit more of that relationship, teasing Han’s first meeting with the Wookie, along with further interactions that signal that they’re establishing the deep friendship that the two characters share by the time we see them in A New Hope.

The relationship between Han and Chewie is something that the film will need to absolutely nail if it’s to succeed: it’s a foundational cornerstone of the original trilogy and is an integral part of the well-loved characters. Solo already has a lot going against it, especially with the film’s well-documented production woes.

Solo: A Star Wars Story hits theaters on May 25th.
