Guardians of the Galaxy director James Gunn shared a bizarre music video for “Guardians Inferno,” featuring David Hasselhoff.

GUARDIANS OF THE GALAXY MUSIC VIDEO FT. DAVID HASSELHOFF

“Guardians Inferno” is featured on the Guardians Vol. 2 soundtrack, and the retro music video is a fun addition to the franchise by Gunn and Marvel. Actors Chris PrattDave BautistaKaren GillanSean GunnPom KlementieffMichael Rooker, and Zoe Saldana all have cameos in the video, as does Gunn himself, Stan Lee, and Guillermo Rodriguez (from Jimmy Kimmel Live!).

But Hasselhoff is the one that steals the show. “Just remember, in these times of hardship: We. Are. Groot,” the actor sings. He bares his hairy chest in a tight white and gold shining outfit. The name of his music video character flashes on the screen – Zardu Hasselfrau.

The video was directed by David Yarovesky but the idea is attributed to Gunn. “The idea was mine, but the execution was all his,” Gunn tweeted Sunday. The featurette will appear on the Blu-ray of Guardians, out Aug. 22. The music video flashes that release date in a retro font. And the very end shows the dancing robot take off his helmet and reveal himself as a very out of breath Pratt.

“Woke up to see #GuardiansInferno w over 3 mill hits on @YouTube & @facebook in under 23 hrs! Movie on digital tmrw!” Gunn wrote excitedly Monday morning.
