William Shatner On Star Trek Vs. Star Wars: 'Star Wars Is Derivative Of Star Trek' (VIDEO)

The original Captain Kirk himself has thrown down in the ongoing "Star Trek" vs. "Star Wars" debate. In an interview William Shatner tweeted today, he expands on the differences between "Star Wars" and "Star Trek," the main one being that "Star Trek" is way better.

"'Star Trek' had relationships and conflict among the relationships and stories that involved humanity and philosophical questions," Shatner said. "'Star Wars' is derivative of 'Star Trek.'"

"Star Wars" did have one thing "Star Trek" was lacking, though -- special effects. But even in that respect, "Star Trek" now has "Star Wars" beaten. Shatner explained that, once J.J. Abrams piled on the effects and placed "Star Trek" within a blockbuster framework, there was a resurgence that allowed "Star Trek" to "supersede 'Star Wars' on every level."

"'Star Wars' has nothing to stand on," he said.

He didn't stop there, and took a stab at the beauty quotient in both franchises.

"Princess Leia, as beautiful as she was, and as wonderful an actress as she is, can't compare to the marvelous heroines we had on 'Star Trek,'" Shatner said. "The pretty girls were prettier than the girls in 'Star Wars.'"

Shatner does note that he would still run off with Princess Leia.

"That would be the perfect union," he laughed.
