Terror at 20000 Feet... Great Episode.. John Lithgow reprised it in The Twilight Zone Movie “ (RIP Vic Morrow)
As I flipped through the rerun channels one night - On Third Rock From The Sun, Here is Shatner as the Alien Boss .. “The Big Head” being met by Jon Lithgow as he gets off an airplane.. Shatner - “Flying gives me the Willies”... Lithgow, “I know what you mean”... He’s always willing to show acting for what it is, Grownups playing make believe.
It’s actually better than that:
Shatner as the Big Giant Head meets Lithgow as Dick Solomon at the airport
