At least I would hope to see a release in Germany, where I understand The Fall Guy may have more enduring popularity than in the U.S. There's a great German TV commercial for Honda SUVs from the 2000s that features an older Colt Seaver (Lee) avoiding obvious stunt opportunities to drive safely:
Pirates aside, I don't think Disney's theme park attractions usually dictate their media decisions. If they did, then Mad Tea Party (tea cup ride) the Movie would be way overdue.
Anyway, the Splash Mountain attractions opened in the late 80s/early 90s, so the only home media tie-in there could...
I don't recall there being a lot of songs on the Fall Guy, but I could be wrong.
The series was streaming on Hulu around 10 years ago, but I don't remember if they had all 5 seasons or just the first 2.
I'm not aware of any recent Fall Guy news, though I'd certainly buy a complete set if it came out. Doesn't appear to be available in Germany either, where the show seems to have a strong following.
Maybe if the upcoming Six Million Dollar Man blu ray set sells like gangbusters The Fall Guy...
