Now I know for sure that The Glenlivet 12yrs is a good whisky. Because of the movie "The Family Man".
Nicholas Cage plays this high flying multi millionaire CEO, that is single. Then, he gets supernaturally transformed into a husband with his wife that he left standing at the airport, when he was starting out in the business world. He wakes up in suburbia complete with 2 kids and a job selling tyres.
He laments his new life. Suburbia, kids, lack of money, the crappy car, the crappy clothes, his job-everything. He walks into his office for the first time and looks at it with disgust. He sits down in the office chair behind the desk and opens the drawer.
And what's inside? The Glenlivet 12yrs! He pours himself a shot and drinks it. And no comment on the quality. So it must be good if he hates everything about his new life but can drink this whisky without complaining.

But on a serious note, I do find it interesting that The Glenlivet 12yrs was chosen as the whisky of choice for this particular scene. As it's something that both a very wealthy CEO would pick up and drink, and yet it's also something that a tyre salesman would have in his office. I know this is only fictional, but obviously the movie directors would have had to take these aspects into consideration when shooting this scene. And they would have had to do their research and choose something that would suit both the lower and upper socioeconomic spectrum, as portrayed by Nicholas Cage in the one character.
I just thought it was very interesting. And that this was the only (initial anyway) item of his new life that he didn't baulk at-something befitting both his new life and his old life.
