Matthew McConaughey put himself through Hell in preparation for his role in "Dallas Buyer's Club". He basically lived the part, forcing himself through a punishing schedule to lose weight to the point where he looks physically ill, and completely committing himself to the part. The least he should have been able to expect from the people making the movie is a little attention to detail when designing the scenery, but alas, no.
Here's Ron Woodruff hard at work in his office, surrounded by the things that motivate him and make him happy. That stetson on the wall, for example, that no proud Texan should ever be seen without. And then that poster of his dream car behind him, too. Woodruff must have been dreaming really big, because way back in 1985 he was capable of imagining, designing and then picturing a Lamborghini Aventador that wouldn't become a reality until 2011.
