Hollywood producers looking to accurately portray intelligence agencies in spy movies can find help in an unexpected place ... the freakin' CIA ... so says U.S. Rep. Elissa Slotkin.

We got the Congresswoman from Michigan on Capitol Hill Tuesday and asked the former CIA analyst about her favorite spy flick, and that's when she dropped a huge bombshell.

Slotkin tells us the CIA has an entire office dedicated to helping Hollywood understand and portray what really goes down between the Pentagon and American spies ... who knew?!?

Sounds like the partnership might have been in play for "Zero Dark Thirty" ... Slotkin says she really appreciated the film as a CIA and Pentagon alum because it at least attempted to be factually accurate -- unlike many movies which are not rooted in reality.
