Funny you mention that... I was binge watching the "Twilight Zone" marathon on Sci-Fy last weekend (complete with Rod Serling's narratives)...

I saw the episode with the Gremlin on the aircraft wing that only one passenger saw (they went and remade this episode in the Twilight Zone movie).

And who was that passenger in this black & white episode? A 22-year old William Shatner /James Tiberius Kirk.

Yikes I'm getting old.
