If you’re a Star Wars fan then you definitely know the name Ralph McQuarrie, the concept artist behind the original trilogy. McQuarrie has worked on some other popular sci-fi franchises, including Star Trek.

After completing work on the original Star Wars: A New Hope, McQuarrie got busy on concept art for Star Trek – Planet of the Titans, which was to be Paramount’s first attempt at a big-screen Star Trek.

While the project obviously didn’t pan out, McQuarrie’s designs were eventually used in Star Trek III: The Search for Spock and in The Next Generation episode “Unification Part 1,” and the artist also officially worked on Star Trek IV: The Voyage Home as a visual consultant.
