Late 80's or early 90's movie
All I can remember is a man that was a cartoonist has his drawings or stories come to life.There's a woman from one of his drawing's/comics or whatever that comes to life and they both try to escape the bad guys or are trying to find a way for the girl to get back to her world.There was a scene inside an apartment where the man took his shirt off to change and the woman saw his belly button and asked if he was wounded in a war.He's confused and doesn't know what she's referring to then she points out his belly button and he tells her what it is but she says that she doesn't have one and lifts her shirt to show a flat tummy with no belly button.The guy then thinks "oh of course" he didn't draw her with a belly button only clothing covering her body so it doesn't exist along with everything else he's never drawn on her.There's lots of action and craziness.I know it's not the movie with Kim Basinger.
