Five films from the hugely popular sci-fi franchise. In 'The Fly' (1958), a scientist (David Hedison) is obsessed with developing a molecular matter transmitter. When he attempts to test the invention himself, he is unwittingly joined by a companion - a fly that has sneaked into the transportation pod with him. The consequences of the experiment soon become clear, as the scientist begins to take on fly-like characteristics. 'Return of the Fly' (1959) sees the original scientist's son reconstructing the matter transporter which turned his father into an insect, with the young man's experiments leading him down the same insectoid path.
