Will Hollywood ever get in trouble for "based on a real story" movies

It is now award season and there was a bit of talk that The Butler wasn't nominated for any awards at the Golden Globes despite all the praise it got and that it is a true story. I looked into it a bit and found out that this "true story" they tell isn't exactly true - yeah, there was a black butler that worked under all those presidents but that's about when it ends. A majority of the story does not follow his life and is made up.

That got me thinking a little - obviously some movies are fictionalized a little for one reason or another but there are some that are pretty much works of fiction. I heard someone in the States was trying to sue a movie studio claiming the trailer for a movie made it seem like one thing when the movies was totally different - she said it was false advertising. Do you think we are going to see more of this happening, especially with things advertised as "true stories" when they clearly are not? If I sold you a pill claiming it would make you lose weight and it didn't, you don't just shrug your shoulders and go "oh well". Look at that guy on Oprah where he claimed the book was his life story and it turned out he made it up - didn't exactly get away with it. Should movies be any different? It is one thing if it isn't mentioned or is part of the credits - "Inspired by/Based on" - but so many movies use it as a part of their promotion that it really is misleading the audience.
