So, I suppose you've been wondering why TNG Klingons have bumpy heads while TOS Klingons have smooths heads? Or is that just me? Well, Sci Fi Wire is reporting that an upcoming episode of Enterprise will deal the subject. (For those unaware, Klingons in “Star Trek: The Next Generation” had alien-looking bumpy heads while the actors in “The Original Series” had no such prosthetics.)
In the episodes, the Enterprise heads back to Earth for the official launch of the Columbia NX-02, Starfleet's second warp ship, commanded by Erika Hernandez. Phlox is abducted by aliens and finds himself in the presence of Klingons who tell him the Empire is facing its gravest threat in centuries. Along the way, as Archer and company investigate and pursue, it’s revealed that one of our main characters has a secret past, which comes into play, the site reporte. […]
I did some additional investigation and discovered that the episode, Affliction is scheduled to air on February 18th. And, as I enjoy Enterprise, I’ll watch the episode when it airs. But I’ve never cared that much about this issue — I just figured that 60s television shows didn’t have those kind of makeup effects. (On the other hand, some Trekkers have completely over-analyzed the subject, to the point of hypothesizing scientific theories within the Star Trek universe which could have explained the discrepancy.)
