Rooster Teeth Productions

 is an American video production company headquartered in Austin, Texas. It was founded in 2003 by Burnie Burns, Matt Hullum, Geoff Ramsey, Jason Saldaña, Gus Sorola, and Joel Heyman, Rooster Teeth is a subsidiary of Otter Media, which is itself a subsidiary of WarnerMedia Commercial, a division of AT&T's WarnerMedia. Rooster Teeth began with the production of the animated webseries Red vs. Blue, which premiered in April 2003 and is still in production, making it the longest-running episodic web series of all time. Since then, the company has expanded to include other animated and live-action webseries, podcasts, video games, toys, and films. Their company name is derived from an insult used in Red vs. Blue, where a character is referred to as a "cock biter".

Rooster Teeth is notable for having history with Ok Goodnight and specifically Casey Lee Williams. At the age of six, she lent her voice to the track "Bye Nikki Bye" in the Rooster Teeth comedy Machinima series The Strangerhood, which was composed by her father Jeff Williams. She later lent her voice to the soundtrack for Red vs. Blue, and later went on to be the primary vocalist for the soundtracks of the Rooster Teeth animated webseries RWBY, as well as the singing voice for series character Weiss Schnee. As of 2018, for the series' sixth season, Casey Lee Williams has intermittently worked with her father for composing for several episodes. She is also the official vocal credit for series villain Neopolitan; despite the character being mute, Williams provided her grunts and noises in the 2018 crossover video game BlazBlue: Cross Tag Battle.

In 2019, for RWBY's seventh season, Ok Goodnight is mentioned by name in the lyrics of the song "Celebrate", which Williams provided the vocals for.

In 2020, for RWBY's eighth season, Ok Goodnight's song "Awake" was used in the episode "Midnight" for a flashback of the villain Cinder Fall; the song was the first to be featured in the series that was not written and composed with the show in mind. It is possible that Ok Goodnight as a whole will continue to have connections with Rooster Teeth Productions, and Williams continues to lend her voice to Rooster Teeth products.
