In Casino Royale, James Bond is required to enter a password into a security device. Later in the film, he reveals that the password he supposedly entered was Vesper...
However, the brief shot we of him entering the code shows him using the number 4, making it impossible that the code be Vesper, as this website points out:
When Bond enters his password in the casino, he enters 836547. He later gives the password as VESPER, which on an alpha-numeric keypad would be 837737.
If we are to take it that this is a goof (which it almost certainly is), it stands to reason that at the time of filming a different password was considered: it's unlikely whomever is responsible for the close-up shot of him entering the code was illiterate enough to enter the wrong code, and even more so for the continuity department not to notice (although, they clearly missed this from the final cut: so it's not entirely implausible).
Could it be possible that another password was originally intended to be used; one that required the keys 836547 in spelling it? can anyone figure out what this original password could have been, before it was (possibly) re-conned to be Vesper?
