Clearly, nobody was killed during the campaign for Jennifer Lawrence's performance in "Silver Linings Playbook." She was joking.
As with any industry, it's not always the best product (in this case the best actor, director, or picture) that comes out on top. That's not to say quality has nothing to do with it. It plays a huge role. Jennifer Lawrence is a good actress. But is she really better than Meryl Streep, Judi Dench and Maggie Smith? In my daughter's opinion, Jennifer Lawrence is the best actress of all time (something to do with "The Hunger Games"). But it's subjective.
Lawrence's win is a clear example of a good quality product, boosted by a well designed and well executed marketing strategy. Harvey Weinstein is well known for his savvy marketing tactics, and he's been incredibly successful during awards season. As far as I know, no bodies have been found.
