So it was incredibly daunting where is -- Judy -- and I would discuss the daunting task of taking on him Jackie O and rob I would discuss taking on JFK and coming -- have played them before -- and it really played many. And I sort of -- what if she was sitting on her couch you know -- and watching with me relax and wanted to make sure they honored her living legacy in every single way. And I would hope that she feels that because I am of Russian descent Seau was might be just -- -- -- -- American. Actress. Just you know -- -- -- -- -- put on the poster in there. -- -- was very intimidating but it did -- -- research and everything that it possibly get my hands on did you speak with their did you did you talk with -- at all. I didn't I knew that. Injuring Warren commission time I believe she -- -- to her husband's guilt and then after immediately after. The decisions came down. She switched everything so that a husband was innocent and I was able to find a YouTube clip. Of her at the thirtieth anniversary and she is very adamant that her husband was and sentenced. And I just never really felt that it would be polite to disrespect. Her -- has our movie does. -- -- the lone gunman theory that Lee Harvey Oswald is the only him -- that shot. Our 35 president.

You still have to be kind of treat yourself and your abilities and -- otherwise he would have been cast for the -- clearly. Yeah I mean though the Russian was the biggest thing -- on my mind so it was less and the fact that she is -- so with less about the adaptation because they think technically -- the the weight of the stress of those kinds of things would fallen -- soldiers arguably he is the title character. But I -- just I worked my. You know -- -- to you. Get the Russian perfected because whereas -- reps speaking Russian this is a completely different form -- -- this is you know how housewife spoke in the late fifties early sixties which is completely dramatically different and the slaying.

I think obviously you misty you immerse yourself in this rolling and you did a great deal homework -- research on this it was something strike you in the work that you discovered. About JFK about his presidency about about his assassination. Well I mean actually a part of it is that I didn't even know of -- existence I actually think most of us don't because you know. It was a moment in time where our royal family. Was at the height of their game where romanticize is -- and and put on a pedestal and then -- and it was the moment that was completely crushed. And you're immediately given -- billing. And you don't think that Dillon has a home life so learning about -- in the was definitely one.
