Do you know where this scene was filmed? If you do, please email me at webmaster@themoviedistrict.com. Full credit will be given to you. Thank you.
Location #5 is a parking garage at 1401 Wilson Boulevard in Rosslyn, VA
It was demolished in 2017.
Is the address right?
I can’t find anything if I browse Google Street View pre-2017.
That Rosslyn address is actually the REAL Deep Throat garage, not the one that featured in the movie, as the real location was unknown at the time the movie was made. It was revealed when Mark Felt finally came out as the real Deep Throat.
Sorry, but I don’t know the location of the movie parking garage, but I have visited the real one, which is much smaller.
The location in the #5 movie still above (bridge on left, staircase, then slab wall with two garage entrances) is in fact in Rosslyn (Arlington VA) and still exists in 2022 and for the foreseeable future. The bridge is still there, the stairs are gone, and the property to the right was redeveloped but they left the bones of the garage with the two entrances. When you find it, compare it to the #5 movie still and it matches perfectly.
You’ll have to do a little sleuthing, but follow the money.
