This is the third entry in Rowan Atkinson's "Johnny English" series. Johnny is about halfway between James Bond and Mr. Bean.
As the movie opens, Johnny's been sidelined, off to a small school where he's ostensibly a geography teacher. But he actually spends most of his time teaching the kiddos spycraft: ninja techniques, disguise, weaponry.
Unfortunately, this is the best part of the movie.
An evil cyberhacker breaks into Britain's "MI7" computers, and outs all the current crop of spies. To investigate, the PM (Emma Thompson, pretty good) demands that an inactive agent be brought back to investigate. So Johnny's off to France to track down the hacker, when he runs into Ophelia Bhuletova (Olga Kurylenko, who was an actual Bond girl in Quantum of Solace). Friend or enemy?
So anyway, Johnny bumbles a lot, a considerable amount of physical comedy, some of the gags work better than others. Atkinson, it's revealed in a DVD interview, likes doing physical comedy. Fine, but know when to stop, OK?
Given the elements, you can write the script yourself.
