This has to be the best Mst3k episode/movie of all time! The cast (only 5 people) was spectacular, and the movie they did was This Island Earth, which is pretty bad for a stupid sci-fi (you call it sci-fi?)movie.
The story of This Island Earth is A big, deep voiced scientist flys to some location in some state (Why don't they tell us where he's going? WHY?) and lands in a airfield, only to find his plane haywire. His plane turns green (or as Mike says, "Well, now I have a refreshing mintt flavor."), and his "sidekick," who looks and sounds like Wilt Chamberlain, investigates the plane attack which should've killed him but didn't. Dammit!
Then, they build this what-cha-ma-call it dohickie lokking talking device and talk with a guy white REALLY white hair, and has a big lump for a forehead. He's the alien. (Oh yeah, a big lump the size of a cucumber is going to hide your identity). Things that didn't make sense: Why did they go to that planet without the oh-so precious element they needed? And, why does the lead woman in the film have torpedo-shaped breasts? (My mom found that out)
Great lines:"I'm not an alien," "This Island Earth can be yours if the price is right!", and my favorite "Then I ram my editor down your throat and lay my egs in your chest, but i'm not an alien!"
