Factual error: As the Hood approaches central London in Thunderbird 2, they fly through Tower Bridge and over HMS Belfast, approaching from the East. However the onboard display in Thunderbird 1 shows TB2 approaching from the West, somewhere over Hammersmith.
Factual error: About 2/3 of the way through the film, the Hood uses an electro-magnetic pulse device to disable the alarms in the Bank of England: the lights in the vault remain completely unaffected. This is rather tame; consider the widespread effects of the EMP devices deployed in 'Goldeneye' and 'Ocean's Eleven'.
Answer: I did hear that Patrick Stewart was on the short list of actors to play the role, but he was in demand of both stage and film. He may have been doing X2 at the time.
