The movie initially had a much larger roll for the torpedo crews -- this was all cut for time (it *was* filmed).
If you've ever heard Chris Roberts speak, you'll know that he was *not* the voice of Blair in Wing II... rather, Roberts posed for the 'FMV' portoins of WC2 as Blair -- ie, the Angel kiss and the like.
He was the voice of the Coventry comm officer in WC3, IIRC.
