PHOENIX (AP) - A made-for-television movie on Jodi Arias is scheduled to air this weekend. "Jodi Arias: Dirty Little Secret" is set to be shown Saturday on Lifetime, but the movie won't be about the trial. Screenwriter Richard Blaney wrote the script with Gregory Small. Blaney told The Arizona Republic (http://bit.ly/19NmBq4) the project was in the works more than a year ago. He says they completed the script in December. That was the same month that Arias' televised trial started in the brutal 2008 slaying of her ex-boyfriend, Travis Alexander, a Mesa motivational speaker. Small says they didn't anticipate the trial getting as much attention as it did. A jury convicted Arias of first-degree murder in May but couldn't reach a decision on whether she should live or die.
