talking of the 6 million dollar man - I used to watch it and noticed that in one episode he took a rife off someone and threw it right across a lake and into the water on the far side
the same clip appeared in the next 2 episodes
and then later on in the bionic woman the same clip appeared
Yeah, 70's, 80's shows used tons of stock footage. They even ripped off each others stories. In one 6 Million Dollar Man story, they're stranded on an island, Steve has to cut open his bionic finger to use a hot wire on Oscar Goldman who needs surgery, to cauterise the wound. Later, he says he cut himself shaving. A Bionic Woman story did the same, and it was a joke when she had the same line...
In Knight Rider, have you noticed when Mike backs up out of the Foundation truck, its never going in the right direction and he does a U-turn on exactly the same bit of road?. Plus he's always racing along the same roads. In some shots, KITT's red scanner is right at the front of the bonnet as in the pilot, but later shots have his front tapered more so the scanner is set back (you can see the large bracket under the car holding the extended front on).
The incredible Hulk story 'Never Give a Trucker an Even Break' used a ton of stock footage from Spielberg's Duel. He was apparently furious at it but couldn't do anything since both productions were owned by Universal.
An episode of Airwolf had a jet airliner crash into the sea & sink ......stock footage from a movie that did the same.
Voyage to the Bottom of the Sea - the 8 window movie sub appears in FX shots in later seasons which should be the 4 window version. Irwin Allen was infamous for using lots of stock footage. In one episode David Hedison (Captain Crane) & a woman hide behind a rock while two dinosaurs fight. That was footage taken from The Lost world (1961)...that also starred Hedison so he appeared alongside stock footage of himself.
