I sure did. “After Earth” sounds like a more commercial version of the title that makes it sound more Sci Fi and about the future. I learned pretty quickly it wasn’t which was disappointing because I think a great movie could be made from the creatures in that book.
If you are unfamiliar, "After Man’ was an illustrated pictography of what wild life might look like after 50 million years of evolution after Humanity is extinct. I saw it once in a library when I was kid but it was out of print for many years. When I came online in the 90s I was able to track down a used copy which was great (the book since came back into print and can be found easily).
