Well, I just read Heinlein's short story "All you Zombies" and thoroughly enjoyed it. Checked into the film adaptation that Sony has in the works. It's called "Predestination" and from what I can see, it turns Heinlein's story of a serpent eating it's own tail into the story of how Ethan Hawke's character doggedly pursues the one criminal who has eluded him throughout his career.
The story was great. I may skip the movie.
