JUST IN: William Shatner, who played the iconic role of Captain Kirk on "Star Trek," has launched into space on a Blue Origin flight. This flight made Shatner, 90, the oldest person ever to travel to space, beating the record set just a few months ago by 82-year-old Wally Funk, who was a former astronaut trainee.

The Twilight Zone: Nightmare at 20,000 Feet was featured in both the original 1963 television show (Season 5 Episode 3) starring William Shatner as well as the 1983 movie starring John Lithgow. The plot follows a nervous passenger on an airline flight who believes that a hideous creature is trying to sabotage the aircraft in the midst of a violent thunderstorm. In this video mashup, we combine Shatner's 1963 performance with the (much more frightening) gremlin monster from the 1983 movie. Enjoy!
