Fantastic Voyage (1966)
In Fantastic Voyage (1966) the scenes of crewmembers swimming outside the sub were shot on dry soundstages with the actors suspended from wires. There was some additional hazard involved because, to avoid reflections from the metal, the wires were washed in acid to roughen them, which made them more likely to break. To create the impression of swimming in a resisting medium, the scenes were shot at 50% greater speed than normal, then played back at normal speed.
As a young boy, Christopher Lee actually met the assassins of Rasputin (Prince Yusupoff and Dmitri Pavlovich), he also met Rasputin’s daughter, Maria in 1976.
