You may find some Land Rovers in a number of British based or set in Britain movies and television shows.

There's The Professionals. But not sure if any Land Rovers were used, been years since I last watched it.
Lovejoy. A Range Rover is used a lot by Lady Jane.
The New Avengers. Two Range Rovers.
Lara Croft: Tomb Raider and/or Lara Croft: Tomb Raider - The Cradle of Life. A Defender but I'm no sure which one got it, or could be in both films.
The Italian Job. A Series II Land Rover.
The Living Daylights. A Series III. Can't tell if a civilian one made to look like a MOD one, or an actual ex-MOD one.
Shaun the Sheep. A Series Land Rover. So what if it is a stop-motion animated series using plasticine, but it is good enough for me. :)

There are many others.

And that's not counting some of the James Bond movies!!
 
There’s an excellent Russian film called ‘stalker’ (yes I am a pretentious film snob) which features some excellent series 11a footage.
 
Michael Douglas had a D2 V8 in Don't say a word

Arnies character in Escape plan had a D2 in Morocco.

Layer cake had a P38 in burn your corneas yellow.

Sniper with Tom Beringer had a smashing Series 1 in the opening scenes.

Clear and present danger with Harrison Ford had several Range Rover Classics in it.

I think it was Mission Impossible 2 that had D3s in it.
 
Doctor Who, revival Series 2 (2006) - Episode 13, Doomsday.

A Series III Land Rover referred to as jeep/Jeep on parallel Earth.
