You might not get the THIS channel -- 117 on my own cable lineup. Or you might have it in your cable array without realizing it.
But THIS has been showing "Outer Limits" reruns. And at 1 a.m. on Friday, there's a decent one from 1963 -- "Sixth Finger," starring David McCallum and Jill Haworth (below). I suspect Darwin never envisioned anything quite like it.
