1935 Washington D.C. Code Breakers

I can't help wondering if this was based on a similar code breaking reality. The detail is so wonderful -- the 1935 era buildings, excluding any buildings newer than that -- the little restaurant called CAPITOL something suggesting an old DC haunt still in existence 80 years after. Elsewhere I saw where Roger Ebert gave it two thumbs up after I had given it 8 out of 10 stars. This was an excellent story line, acting, directing, quiet, and engrossing. The U.S. Navy uniforms, in fact all the clothing suggested to me that it was 1935, even the Navy's limousine. I derived 1935 from their hints about a problem 7 years prior in Tokyo, and from the speculation about FDR's re-election in 1936. The "sets" were stark and spare just as I'm sure buildings were in 1935, a spartan time for all, including the Navy. I liked it for its overall air of authenticity. Did the little spy cameras really come from Latvia in the 1930s? If so, that's amazing detail.

Oh, I have one criticism -- on the English subtitles. The typist referred to the thief as Enson Doyle, when most of us spell the beginning rank in Navy officers as ENSIGN. ENSIGN Edward Doyle -- would have worked better.
