Allison, I'd definitely recommend Hi Mom! It's very different from typical De Palma in that it's more influenced by French New Wave than Hitchcock. There are Rear Window elements, but it's mostly played as comedy. Mostly, because there is one pseudo-documentary section that, for me, is the most harrowing sequence De Palma has ever done. What's your favorite De Palma? (mine is Dressed to Kill).
