Stalker managed to catch some of the recent oil based drama called Landman, an updated Dallas one might say.
There was a scene where a meal is cooked and truffle is used - a $2800 mushroom as the titular character played by Billy Bob Thornton exclaims.
The meal in true dramatic style ends up sliding down a wall.
Just as in The Ipcress File with Michael Caine, it's always amazing how a mushroom scene can punctuate a movie or mini series- the import of the scene is always something freighted with deep meaning pertinent to the drama.
