Movies always cut out the hours of time a true professional like Bond would be spending in his study, before a mission, learning and planning.
The late nights, one drink too many or one drink too few, pouring over maps and reading materials about the places and the people. Perhaps some language study. Maybe some casual research of police tactics and security apparatus. You can never be too careful, ya know.
To some people those hours would seem like long, boring drudges- like being back in school. But to those who know the power of these sorts of things, there is nothing better than a quiet night devouring scotch and knowledge.
