Ok, I have two movies I've been looking for, The first one has Arnold Schwartzeneger or however you spell it and his daughter gets kidnapped, I also remember someway into the movie he sticks a pipe into somebody. The second movie I don't remember much except there is some kind of alien or something that sucks your brain out of your head and only leaves a small hole. Can anybody help?

Ok well I found the first one. It was called Commando

This is a longshot, but there is an alien bug in this movie that sucks brains. Not a big part of the movie plot though...

Starship Troopers (1997)

If that's not the right one, is there any other clues you can give? Alien size, shape?
