Revealing mistake: When Al picks up the locket from the coffin, it emits a sort-of ethereal, magical "glow." However, you can see where this glow simply "ends." There is a hard, square-shaped line around the glow where it simply stops. Poor blending of the effect. (This is best visible in the Blu-Ray, but is also visible in the DVD and VHS versions).
