is it Full Metal Jacket

it may be from full metal jacket...ask full metal jacket bout that, its his username so he must have the whole script memorized....

Hi, it's Nick,
There must be someone out there who has seen the Movie with the dialogue I've posted.

I believe I can be a bit helpful.
The actual quote should be "liking leads to lovin.. lovin leads to ****ing.. and no one ****s Warren".
But then again don't ask me where that is from.

That is Gunnery Sergeant Hartman speaking there, sounds like him alright.

Hi, Nick here again. I still do not have an answer.

its not Full Metal Jacket. i just watched it a few days ago. i cant remember the movie the quote is from though.

I'm stumped on this one. It's definitely not Full Metal Jacket or Hamburger Hill. I have seen, what I would say, quite a lot of movies and I have never heard this quote in any of them. You sure it was in a movie?

well, i googled it
and it brought me to this

and that was the only result

i googled it too, and i get nothing about a movie. i get one thing about a DI saying it, but nothing else military.
