When Drysdale returns to the bank and is explaining to Jane what went wrong with her million dollar idea he walks into his office and hangs his hat on the hat rack that is now on the left side of the door when earlier it was on the right.
In the shot of the armored truck sitting in front of the bank as Jane and Drysdale walk out they both brush against a low hanging limb of the potted plant but when they switch to a close up of just the two of them the plant has been moved a little to the left and the low limb is gone.
Jethro was inspired to become a double naught spy from seeing the movie "GOLDFINGER" that was released in 1964 however when they show the stock footage of the people walking their dogs around the track at the dog show there is an American flag on the right when unfurled clearly shows the 48 star pattern (6 by 8 stars) which was changed to 50 stars in 1959 when Alaska and Hawaii were admitted as states.
