Plot hole: After Hannigan feels guilty for what she did, she confesses to the girls, and they find Mr. Stacks to tell him. The fact is, they went straight to where he worked - but Annie never told them the destination, and Guy himself never told Hannigan where it was either. So, how did they get there, and most importantly, know where it was?
Continuity mistake: When Stacks spits the mashed potatoes on the homeless' face he has bits all over. In the side shots his face is clean. This changes back and forth.
Continuity mistake: When Hannigan throws the Annie shirt at Lou he picks it up in one hand and moves it to the other hand which he lifts up in the next shot but when he does it is either in the original hand and out of frame or else completely disappeared.
Answer: In earlier versions of the "Annie" story, she is orphaned when her parents are killed in a car accident. In the musical, they died in a fire. In the 2014 re-imagining, Annie lives in foster care after being abandoned by her family. Early on, she hopes to one day be reunited with them. We, the audience, never learn their whereabouts, nor whether they are alive or dead.
