October 6, 1967 –
Kirk, Scott, McCoy and Uhura enter a parallel universe in the Star Trek episode Mirror, Mirror, which aired on this date.
It took about a month to complete this particular episode. After filming had begun, BarBara Luna was diagnosed with strep throat. Since the script called for Capt. Kirk to kiss her, they had to postpone the kissing scene for three weeks until she was medically cleared, since they couldn’t risk William Shatner getting infected. (I’m sure Bill would have risked it.)
