I misread the above post when I first saw it - I though it said "Samantha Bond would have been great on Fields."
Ditto "How about Q, on Fields?"
Gives a whole new meaning to "I hope you don't snore, Q."
Anywho, I shouldn't be surprised if Q ends up forced into the field along with Bond in a future episode. It will probably turn out like Henry Jones Sr & Jr, or Bruce Willis & Justin Long in Live Free or Die Hard, where the tagalong holds up the hero until he finally gets his moment to shine.
Better low-key climax:
Bond vs Kanaga in the grotto
or
Bond vs Whittaker in Whittaker's private war museum?
