2. Millennium bridge:
The main character can be shown walking down millennium bridge
towards saint Pauls cathedral in the opening sequence. This would be
effective as it shows one of the iconic sites of London which establishes
the location well.
3. SIS building(MI5/MI6):
This building is where the MI5/6 operate and has featured in films such
as James Bond and is iconic in the in the city landscape. Using this
building in an establishing shot would express to the audience that the
opening is set in the MI5 building and that the main character works for
the secret intelligence.
The Thames path or river side walk gardens area has a clear and un-
obstructed view of the SIS building which would be effective when
shooting an establishing shot for the opening.
