Watch Robert Englund become Freddy Krueger one last time.

Back in 2014, Robert Englund appeared at Chicago’s Flashback Weekend and provided fans with a once-in-a-lifetime experience: he was fully decked out in Freddy makeup, allowing diehards to take photos with him as Krueger for the first time. Talk about a memory you’ll never forget, huh? If you missed it, don’t be sad. Because a new documentary will soon peel back the curtain.

Directed by Mike Kerz, the upcoming doc Nightmares in the Makeup Chair was primarily filmed at Flashback Weekend, and in it Englund shares behind the scenes stories while FX artist Robert Kurtzman applies the makeup. The doc, hitting the festival circuit this year, will “take fans on an exciting, funny, and emotional journey through Englund’s years as Freddy Krueger with stories and anecdotes, all while paying tribute to the legacy of Wes Craven.”

Kerz explains why he wanted to make the doc:

I was inspired by the vintage photos of the legendary artist Jack Pierce applying the Frankenstein makeup to Boris Karloff. Sadly, those sessions were never documented on film. That is why we created our documentary – fans will see two modern horror legends at work. Robert Englund is fascinating as he shares insightful stories about the Elm Street films and Freddy with the audience. And it is amazing to watch Robert Kurtzman apply the various stages of makeup to transform Robert Englund into Freddy Krueger.

Adds Englund himself:

Nightmares in the Makeup Chair is my love letter to the Nightmare on Elm Street series and to practical makeup. I’ve always been in awe of the multi-talented makeup effects artists. From sketching to sculpting, they realize the design. Then to the fine precision of the molding and the manufacturing of the makeup appliances which are nearly paper thin. And then, the application process where I sit in the makeup chair and I become their living canvas as they glue me in and paint the appliances. This documentary not only captures their talent, but I think it might inspire a new generation of practical effects artists. I was happy to become Freddy once again to share the makeup process with the fans.
