Poor Bastards of Cinema: The Puppet Masters

 After some consideration, my original pick for this one doesn't quite pan out.
Plan B.

In The Puppet Masters, alien parasites control people.  Simple stuff.

Our Hero is controlled and uses his connections to get close to the guy in charge of Security for The President's arrival.

And yes, it is the guy from Dirty Harry.

Naturally, our Hero (and his previous victim) get two new helpers for their mission.

Ouch face.

Said men then set up The President for an alien parasite of his own!

...but the good guys show up to kill them.

I guess they didn't feel like trying to, you know, capture them and free them from the parasite.

So they're dead.

The original pick was the first victim (used for this set-up).  The problem- he doesn't appear in this bit.  At all.

Seriously, he's not shown being killed or saved.  
Maybe he's behind the door that (initially) traps the President, but we get no closure on-screen.

Oh well, I'll settle for these Poor Bastards instead.

The moral: just assume that anyone could be an alien's host.  Look what happens when you don't!

Next time, some people try to help a woman in need.  They're also quite keen with running up to fight a Cop, which is odd.  See you then...
