There's always a lot of talk about "lost" films from the 1970s and before that are either becoming available or need to be made available. I love the cinema of the 1970s as much as anyone, but with the fading of DVD and Blu-Ray into a collectors' only marketplace, and with fragmentation and inconsistency in streaming services, you might be surprised at some of the more recent films that appear to be falling through the cracks.
I've picked four such films. Some of these are moderately big name movies or involve name directors or stars. So there is hope that they will permanently find their way on to a streaming service or to being in print on DVD/Blu-Ray.
Availability is, hopefully, subject to change, and I hope you will let me know in the comments if you know of a place where these films are (legally) available that I've missed - particularly for streaming.
