This came about from an earlier tumblr post that was itself inspired by watching Frankenstein and the Monster from Hell. Cushing has a scene where the monster is rampaging, he whips his jacket off, wraps a bottle of ether in it, smashes the jacket against the stone wall, bounds to the top of a table and leaps onto David Prowse's back, smothering him with the jacket.
I checked his age at the time. 61.
The Tumblr post answer is, no, Cushing didn't run down the length of the table and rip the cutains off. It was his double.
But the point was the energy amperage that Cushing threw into stuff like leaping across tables, turning over in chairs (Dr Syn)
Diving and skewering Mummies with wall displayed spears.
You always believed he could do everything you saw. Very heroic.
I did a couple of thumbnails of Cushing spearing the Mummy and then looked up reference. You can see how much energy I wanted to put into the scene vs how much exists in the stills. That's the effect of Cushing throwing himself into the scenes.
