1 revealing mistake - chronological order
Directed by: Michael A. Simpson
Starring: Michael J. Pollard, Pamela Springsteen, Mark Oliver, Tracy Griffith
Other mistake: At the beginning of the film, there's no way Angela would possibly have been able to know the exact moment the girl would have been walking down the street and what she'd be wearing so she could be wearing the exact outfit.
Cindy: I like movies with really good acting, like Gone with the Wind or Care Bears.
