I should give a disclaimer up front that I have not seen Ken Burns' series "The Roosevelts," which includes considerable material on both Franklin Roosevelt and his wife Eleanor - although I've heard it's weaved together fairly well (and tells their lives in parallel), I am somewhat put off by the length of the series, and feel no particular need to watch it anyway - at this time, at least - when I have this fine film about FDR (and another about his famous cousin Theodore Roosevelt). Perhaps I will get around to watching it someday - I've heard that it's sometimes available on Netflix - but for now, at least, I'll confine my made-for-television biographies of FDR to this classic one by David Grubin; who is also the maker of PBS's films on Lincoln, Theodore Roosevelt, Truman, and LBJ. (I might also note one other thing about this filmmaker, which is that he made some films about a few notable Europeans as well, such as Napoleon and Marie Antoinette, which are also quite good.)
Franklin Delano Roosevelt
As mentioned in the previous paragraph, this television biography of FDR is quite good - with plenty of real photographs and footage of him, it manages to tell the story with considerable interest and visual detail. It has interviews with his descendants (along with some former members of his administration and a number of scholarly talking heads); and there's also a notable interview with one of Churchill's daughters, where she comments on this famous relationship between the two men, which was one of the great and important relationships of World War II. FDR actually got us involved in the war long before Pearl Harbor, with the Lend-Lease aid to Britain, and the Navy's involvement in the Battle of the Atlantic. Although not many would appreciate it today, FDR was pushing the envelope on what Americans would tolerate in this area; and he may have helped save Britain by his successful advocacy of (at least some) early American involvement in the war.
