Did You Know?


The budget-strapped show often made good use of the creativity of its prop staff in coming up with low-cost solutions to otherwise pricey items. Here, the "thermal suits" worn by Spock and Tormolen on the planet's surface were fashioned from 1960s art deco style shower curtains. See more »


There seems to be no rhyme or reason to how the infection is spread. Sulu and Riley are infected from fighting with a fully-clothed Joe Tormolen (but they did have contact with Tormolen's blood after he stabbed himself), and Chapel by a calm Riley, but Uhura, despite being manhandled by a sweating, stripped-to-the-waist Sulu, is not infected. People's immune systems and tolerance levels vary. See more »

Madness Aboard The Enterprise
20 December 2016 | by Rainey-DawnSee all my reviews

Season 1, episode 4. Mr. Spock and Lieutenant Junior Grade Tormolen the Psi 2000 to find out what has happened to the people. Everyone there was dead but it doesn't add up... one even died taking a shower with his clothes on. Spock and Tormolen re-board the Enterprise but little do they know Tormolen has caught a mysterious disease while on Psi 2000. Tormolen ends up infecting Mr. Sulu and others. Strange behavior takes place among the crew of the USS Enterprise. Tormolen overrides the bridge, it's controls and intercom -- the ship is speeding towards the planet with Kirk, Spock and Scotty racing to get back control of the ship while Dr. McCoy quickly trying to find a cure. Can a cure be found before it's too late?

A really fun episode watching everyone on board the ship acting out of character - in particular watching Sulu's swashbuckling scene!!
