Enlarge / Sara (Mary Nepi) and Hayley (Gabrielle Elyse) team up to save their Arizona town from an alien invasion in Snatchers. (credit: Stage 13) A teen pregnancy goes horribly awry in Snatchers, a charming genre-bending send-up of B-movie creature features, infused with the anything-goes spontaneity of sketch comedy. The horror/comedy debuted last weekend at the SXSW Film Festival in Austin, Texas. (Mild spoilers for Snatchers below.) High school student Sara (Mary Nepi) is pretty and popular, but she's also just been dumped by her hunky boyfriend, Skyler (Austin Fryberger) because she wanted to wait to have sex.
