Continuity: Charlene and Jack are kissing by the water and Charlene is pulling her shirt up. You can clearly see that she is wearing a bra (also later you can see her bra through the wet shirt). But when she finally does take the shirt all off, she isn't wearing a bra anymore.
Factual errors: In the scene where "china doll" is analyzed, they misspell PHILIPPINES as PHILLIPPINES.
