Casting extras for "Jack of the Red Hearts," a feature film starring Anna Sophia Robb, Israel Broussard, Scott Cohen, and Taylor Richardson. Synopsis: A streetwise teenage runaway is on the lam from her probation officer. Her name is Jacquelyn, but if you call her anything but Jack, she’ll cut you. Needing to lay low, earn money, and gain adequate stability to rescue her 11-year-old sister Coke from foster care, Jack cons her way into a suburban home as live-in helper for their autistic 11-year-old daughter, Glory. Much to her surprise, Jack has a unique ability to connect with the nonverbal little girl. As she positively impacts Glory, the family impacts Jack. Particularly Kay, Glory’s mother. As these two scrappy survivors find an affinity with each other, Kay finds in Jack a daughter she can talk to. When romantic sparks fly between Jack and Robert, Glory’s 17-year-old brother, we see a group of wounded people poignantly and surprisingly begin to heal each other---just a little bit. But the law catches up, the truth comes out, and Jack is forced to make a choice---to save her own hide, or save someone else.
