People naturally think that Mosquito Squadron was a sequel to 633 Sqn for this and other reasons, but it wasn't really, it was just as way of keeping costs down on a budget film, so made sense to not re-invent the wheel.
Mosquito Squadron was actually the 3rd in a 5 film plan of war theme movies made in the late 60's on the back of the success of 633 Squadron.
From Wiki:
Encouraged by the worldwide success of 633 Squadron, producer Walter Mirisch proposed a series of British made films with a military theme having major American stars in the lead that would comply with the Eady Levy requirements and cost no more than US$1 million.
Attack on The Iron Coast starring Lloyd Bridges was the first of the series of John C. Champion's Oakmont Productions and began shooting in May 1967. The others were Submarine X-1, Hell Boats, Mosquito Squadron, The Thousand Plane Raid and The Last Escape. Each of the films was approximately 90 minutes long making them suitable for half of a double feature and had a Hollywood star leading the cast.
