The Unborn

• When Rabbi Sendak opens the Hebrew book in his office, he thumbs through it in the wrong direction. Hebrew is written in the opposite direction to English; a real rabbi would have opened the book and read it from right to left.
• Movie Goof (continuity error): When the professor lecturing is shown far away the word "Before" on the chalkboard behind him is completely underlined. Next time the professor is shown in his closeup, only part of the word, "Befor" is underlined. The letter "e" is clearly NOT underlined. Then afterward, he is shown in a blurry mid-shot, the word "Before" is completely underlined once again.
• Rabbi Sendak's name is a reference to Maurice Sendak, writer of children's horror classic "Where the Wild Things Are".
• Movie Goof (continuity error): In the club scene, after entering Mark asks Casey, Romy and one other girl if he can get any a drink from the bar. Romy and the other girl orders a drink. Casey says no. As soon as Mark walks away to complete the order, Casey begins to walk through the club already holding a drink.
