I think I saw this scene in a movie in the ’90s, and I thought at that time that the (colour) movie had been made quite recently. At some point I thought it was Army of Darkness but I’ve since watched that and did not see the scene. Perhaps an alternative version?
In the scene the Ash-like hero is driving his sweet convertible through rough terrain with his best Sheila-like girl by his side. It felt like the end of the movie but may just have been a pivotal moment. He suddenly slams on the brakes, and as the camera pulls way back to take in the entire situation, we see the car is stopped before a huge cliff with (if I recall correctly) Deadite-like creatures crawling around everywhere.
And that’s all I remember. Ring any bells for anyone?
