It’s Batman Day, which means it’s time to celebrate your favorite Caped Crusader. For Will Arnett in the new Lego Batman Movie poster, that would be himself.

The mini Dark Knight leaps into action in a new one-sheet image for the film, which touts some pretty solid advice: “Always be yourself, unless you can be Batman.”

The poster helps mark Batman Day, which launched with the character’s 75th anniversary celebrations. This year, fans have the opportunity to get some free swag in the form of the Tom King-penned Batman #1 comic from DC’s Rebirth. Six Flags, Barnes & Noble, Pottery Barn Kids, and other establishments are participating, while guest talent including King and Frank Miller are appearing foo meet-and-greets at various locations.

Arnett voices Batman in The Lego Batman Movie, a spin-off of The Lego Movie. Directed by Chris McKay, the film features Rosario Dawson as the voice of Batgirl, Michael Cera as Robin, Ralph Fiennes as Alfred, Zach Galifianakis as The Joker, and Mariah Carey as Gotham City Mayor Marion Grange.

The Lego Batman Movie is set for release on Feb. 10, 2017. Check out the new poster from Warner Bros. below.
