I agree that the movie "The Invaders" had its problems, it was long and tedious, and sometimes confusing. But to diss a movie because of Factual errors? Its Hollywood; what did you expect? them to hire Physics experts to give them the information to keep these factual mistakes down? raoulfenderson must be such, maybe he or she should offer services to Hollywood.. I enjoyed the movie for what it was, a movie, even though it was low tech, and tedious sometimes, as I believe the makers were shooting for. After all, the movie was based upon a somewhat campy/cheesy TV show from 1966/1967. As I write this, I am watching the series on SciFy Channel, just as cheesy as the movie, but just as enjoyable as the old days...
