So if you are going to go hit up the new sci-fi/western movie Cowboys and Aliens (opening in theaters July 29th) just know going in that it is a movie based off of a graphic novel.  No big deal there, right?

Well, the odd thing I learned this week is that the graphic novel itself was inspired by another piece of artwork.  In particular, a Gary Larsen Far Side comic.

Wait,….what?

Take a look.

Well, you don’t see that everyday. In 2006, Platinum Studios published the 100-page graphic novel created by Scott Mitchell Rosenberg and written by Fred Van Lente and Andrew Foley, with penciler Luciano Lima.

And this month we see the movie staring Daniel Craig (James Bond), Harrison Ford (The Frisco Kid), Sam Rockwell (Galaxy Quest) and Olivia Wilde (Year One) and directed by Jon Favreau (Iron Man).

Here’s a look at the movie. A $140 million adaptation of a Far Side Cartoon!
