I remember in the late 90’s a bunch of comics came out in the vein of Men in Black (which was also a comic, just in case you didn’t know) and R.I.P.D. was one of them. I remember actually reading it, I thought it was OK. I think it was originally just a 4 part comic series and I never bought anything past that simply because I thought the story was a straight rip off of Men in Black (which in all honesty I thought was a rip off of Ghostbusters).
This trailer looks like it is a clear Men in Black take on the comic, but I definitely remember the two main characters, especially the cowboy sheriff.
Let me know what you think:
