It scared the crap out of me when I saw it in the late 70's on television.
(That's what happened to movies back then... they went from the theaters... to Teee Veee. Cool 'eh)
Now it's a brand new movie called "I Am Legend" staring a black version of Heston... Mr. Will I Used To Be A Rapper Till I Got All The Money On Earth Smith.
I will be curious to see this new one... but you know... the old versions suck on the freaky effects and make up for it by actually trying to get at the original story line and bring some of the authors "cool idea" to life. Watching the trailers... IAL looks a bit like another serving tray for Will To Get Jiggy Wit Da Bad Guys.
