In Orphan (2009), when they speak of the fire that Esther survives that is seen at the end of this movie, they refer to the family as the Sullivans. In this film, the family's last name is Albright.
Around the 1hr 8min mark, when Esther/Leena & Allen are in the studio at night painting together, initially Leena is painting a tear under the left eye on Allen's portrait, but as Allen leaves the studio, the tear is shown trickling down from the right eye.
Esther's record player and the 7-inch Jimmy Durante record are an important plot point but in every shot, it's obvious that the record is missing the adapter needed to play a standard U.S. 7-inch record with a large hold on a standard spindle.
The prescription bottle gives a fictitious address in Connecticut, but the ZIP Code is half a continent away, in Kansas City, Kansas.
When Esther is driving the Ranger Rover, the ribbon on her left wrist changes positions between shots, revealing no visible scars.
Taking the record from Esther's room to dust for prints was a poor choice of items for a seasoned police detective. There would have been many items better suited for this. It's completely believable that Esther noticed the missing record almost immediately, v.s. maybe a less conspicuous object. Add to that, the grooved, bumpy surface of the record would likely not keep a print very well v.s. an item with a smooth surface such as a hair brush or a drinking glass.
