The people behind the HBO series "Luck" are getting sued over allegations that they abused several horses during production.

Here's the story from Fox News:

HBO’s canceled series “Luck” has proven to be anything but lucky for the network.

The show was shut down in March 2012 after four horses died in production. Now, a woman who worked with the show is suing HBO, claiming they aided in covering up alleged horse abuse on set for months.

Barbara Casey, who worked for the American Humane Association for 13 years, is suing her former employer, HBO and Stewart Productions, claiming she was terminated after she blew the whistle on the horse abuse.

According to the complaint, filed in a Los Angeles court and obtained by The Hollywood Reporter, Casey witnessed horses being “drugged to perform” and horses that were “underweight and sick.”

In the suit, Casey claims producers ignored the alleged abuse, though she urged them to report it to authorities. She was then fired in Jan. 2012.
