I don't know the title, story and age but there was a very early film, made in England, in which a train crashes at speed into a steam-waggon on a level-crossing. I don't know if this used real but withdrawn equipment – if so it must have taken some doing to time the train and wagon accurately.
The film "The Iron Maiden" used an extremely accurate wooden replica of the eponymous Showman's Road Locomotive for the bits where no real SRLs were to be hurt in the making.
I suppose BR or Network Rail could claim similar when it deliberately ran a withdrawn diesel locomotive and coaches into a nuclear-waste flask filled with inert material. The video, intended to show the integrity of such flasks, shows the loco was fitted with some form of "remote control" set in operation from an external point below the sole-bar, so no-one had to jump from the cab.
