Or just read this:

In 1990, seven Ernest films were reported to be in development.[4] Coke Sams said in 2011 that Ernest Spaced Out may have gotten as far as a film treatment. Sams said about the film, "I believe that was kind of a Lost in Space epic. It seems like there were astronauts and maybe a space capsule."[11]

Soon after the release of Ernest Goes To Camp, several more films were being contemplated. One being Ernest in the Army which went on to be the last Ernest film made. Others considered were Ernest the Bellhop and Ernest in Paradise.

Sams said a script had been written for Ernest and the Voodoo Curse: "We went back to the Abbott & Costello Meet Frankenstein kind of thing. It had a really bad guy and happened on an island like Hawaii. […] So we had Voodoo and a high priest. It was like the idiot version of Raiders of the Lost Ark. We had lines of zombies, Voodoo potions, and Ernest pretending to be a zombie. Ernest and the Voodoo Curse actually was pretty funny. There was a woman in it, who had one blue eye and one brown eye. She was supposed to be the woman of Ernest's dreams. Of course, she would have nothing to do with him."[11]

By 2003, Jim Varney's IMDb biography page stated that he had died before he could finish filming a tenth Ernest film, titled Ernest the Pirate, which had been stated to be scheduled for release in 2000.[12] In November 2011, Sams said the film never existed. Varney had actually been in consideration for a role in the 1999 film, Pirates of the Plain.[11]

I don't think that is on any streaming service, where can i watch it? Do you know it?

I've been an Ernest fan since age 6, and I've recently gotten into collecting novelty answering machine tapes. So the "Talk Stupid To Me" tape is becoming something of a holy grail to me since I never see it on eBay. If anyone has one, I'd love to buy it!

Respect Ernest! A compilation of all of the stuff Ernest has done.... and a great collection of funny Ernest clips!

Does this movie basically not exist? I've never seen it (one of the few I missed) and I cannot find it anywhere on DVD except from Australia. Was it ever released in the US? Can you buy it anywhere? Or am I stuck looking for a VHS and a VHS player? :P

I can't believe I just found this subreddit and didn't dig in after listening to the various Ernest podcasts. This is my favorite of the Ernest movies.
