I'm a lurker who finally just created an account because, after many, many hours, I completed a fan edit of The 1986 film where Prime survives and stars in the film -- "Transformers: The Prime Cut." Believe it or not, the movie isn't all that different.
I'm no Orson Welles, but using re-purposed footage and audio clips, it's a semi-convincing edit. I probably did this as therapy to get over my 35-year trauma from Prime's death. There may be no demand for this whatsoever, but please let me know if you want it, and it's yours.
Either way, I posted it on the internet archive because, I figured, since Transformers (1986) was already posted and streaming on that site, it's hopefully legal.
