The 1977 paperback version of "Dune" I had to read for a Literature essay (on water symbolism - shudder) had a large circle on it, "Soon to be a major motion picture". The movie didn't come till December 1984.
Heck, I used to have a paperback edition of THE DEMOLISHED MAN from around the same era that featured a similar starburst--and I'm still waiting for the movie!
True story: I once acquired a suspense novel for Tor, in part because there was a Big Movie Version in the works. But years went by and production on the movie kept getting delayed. The book came out in hardcover, trade paper, mass-market and eventually went out of print while I was still waiting for the movie to happen. I finally gave up and reverted the rights back to the author.
And, you know, the movie still
hasn't started filming . . . .
