Bassingbourn question?

I’m sorry to bring up such a trivial matter but it’s regarding the 1944 docu-film ‘Memphis Belle a story of a flying fortress’.

In the initial scenes a parish church can clearly be seen in the background with M.B. in the foreground.
Knowing that the 91st BG were based at Bassingbourn and I live quite locally I went searching for this church.

The church in the footage has four corner turrets but I could not find such a church in the area surrounding Bassingbourn barracks. The only one in fact is Royston church itself but that’s several miles away. The church in the film is situated only a few hundred yards away from the aircraft.

I suspect the early scenes were filmed elswhere, does anyone know which church this is?
Many thanks,
N.o.n.
