The film that is referred to here is "They Made America" by Harold Evans, who did a 15 minute segment on Giannini.
A.P. was a BIG FDR supporter, even though the Dems screwed him on his nation-wide branch banking bill. FDR did, apparently (and this was something Bonadio didn't bother to check) allow the BofI to reopen in the "Bank Holiday," even though by government standards some think it was not solvent.
Thanks for the very interesting information. I have not seen that covered in anything I've read on FDR, that I can remember.
