I’m trying to find the name of a movie I watched about 10 to 12 years ago and can't remember the title. It was like "The Boys From Brazil", but was about a secret world wide organization of Nazi war criminals headed by the camp doctor. The doctor was suppose to be the son of one of the camp doctor's but in fact was the original doctor who had found a way to make all of the ex-nazi people younger. He had experimented on children, and found something from them would reverse the aging process. As soon as a group hunting this organization would get close to a member, that member would be killed to protect the group. Members come to his clinic for treatment in a guarded castle in europe. A group of CIA people are trying to find out if this organization really exists. They finally discover where his clinic is, and enter through old caverns up the hill behind the castle. Much mystery. Don’t remember any of the actors!
Please help if possible. (dick4711@mchsi.com)

I don't know if I am correct on this, but could it be Marathon Man? It is about a Nazi war criminal of sorts. The link to the movie is here: http://www.imdb.com/title/tt0074860/

The Internet Movie Database (IMDb) will get you about anything you need. This movie has Dustin Hoffman in it. It was made in 1976.

It doesn't sound like Marathon Man. That was the one about the Nazi dentist, right?
