Hammerstone Studios

Background
Hammerstone Studios is a film and financing production company, launched in 2018 by Alex Lebovici and Steve Ponce.

1st Logo (September 8, 2018)
Visuals: Panning down from space, we see a rocky cliff with the company name in a chalky texture in it. The "O" in "HAMMERSTONE" is a stylized circle, and three lines then draw on it. In the background, the sun rises.

Technique: 2D animation.

Audio: None.

Availability: Only seen on The Public. It also appears on this Deadline article.

2nd Logo (June 9, 2020-2023)
Visuals: Similar concept to the previous logo, except redone in CGI. On a dark blue space background with a shooting star, we pan down to reveal a cliff against a cloudy sky with the stacked company name in a more royal blue different font, the former in Copperplate and the latter in a normal font.

Variants:
 * On Bill and Ted Face the Music, the logo is reversed, transitioning into the film.
 * Sometimes, the logo is still and slowly zooms in.

Technique: CGI.

Audio: None or the opening/closing theme of the movie.

Availability: First seen on trailers for Bill and Ted Face the Music and later appeared on the film itself. It was also seen on the end of Barbarian.

3rd Logo (July 28, 2023)
Visuals: We start off in space, very much like the previous two logos. The camera then pans up and moves toward a gap in a golden canyon with a river at the bottom of it. After that, we travel through an area with plants and an orange mountain behind it. The camera pans up to reveal the company name (retaining its appearance from the 1st logo, but in 3D), and a star is seen shooting in the background as it is revealed. The logo then cuts to black.

Technique: CGI, just like the previous logo.

Audio: The opening theme of the movie.

Availability: Seen on Sympathy for the Devil.
