But there's also a lot of FYC campaigning leading up to that point where critics and Golden Globes and others are nominating actors very much based on studio marketing/advertising, so when Kieran Culkan is being considered supporting and nominated/winning there and Zoe Saldana is the same, other groups are just going to follow suit. There have definitely been attempts to rectify category fraud like when Kate Winslet was nominated for supporting for The Reader (I think) in SAG, but the Academy acting chapter put her in lead... and that's where she won. Keisha Castle Hughes was nominated in the supporting category but she was clearly the lead and the Academy nominated her there. Sometimes it backfires when people couldn't figure out whether Scarlett Johansson should be a lead or supporting for Lost In Translation... and she got nominated in neither, maybe because the actors weren't sure and she ended up in both. In one of the critics groups where I ran the elections for years, we'd get actors who would get nominated in both lead and supporting and the way it worked is that if they won for supporting, they're removed from lead. If they LOSE for supporting, they can still be eligible to win for lead.
