William Shatner had his chest shaved for this episode. In the next episode to be aired, Star Trek: Where No Man Has Gone Before (1966), he clearly has a hairy chest, as that episode was filmed a good year before this one. See more »

Star Trek

Charlie X

A cultural hub and by far one of the most loved and respected tale, Star Trek is created by Gene Roddenberry who wrote this brilliant concept, ahead of its time and is probably why it still doesn't fail to entertain us after these many years. It was written "for the future" in many aspects as it even though is smarter, wiser and powerful it still seeks for emotion and the force that binds it all. The relation between Spock and Kirk; despite of its premise, is the most human thing in this majestic tale where the adventures are endless. Encountering this original series, at this stage makes the execution look petty and a bit loose (the small technical aspects can be negotiated) but the writing is smart, gripping and hence completely overpowers it.

Unlike any other hit series, it only has 3 seasons so luckily it means that they will be covering up all their ideas within it until they are satisfied. As it often happens, the first season is always promising and has potential (or else it won't lift up for further more seasons) in it and is utilized with fine detailed work like focusing on different new breeds and characters bonding through this journey.

A brilliant premise that is written explicitly on paper with fine details and gripping screenplay that is focused throughout the course of it and doesn't spend its time on petty emotional drama. Ticking for an hours, it offers enough material and creates a sense of urgency and a critical state of danger which shows the excellence in execution.
