'You Can See Everything' tops slow Halloween weekend box office

The film has now earned $63.88 million domestically, Boxoffice Pro reported, and AP said it reached the top spot in its third weekend. "Clayface" won Halloween Saturday itself but finished just behind over the three days, according to Boxoffice Pro.

Boxoffice Pro said the narrow gap could change when actual figures are reported on Monday.

Why it matters: A documentary leading the weekend box office is rare, and the result came during one of the year's slowest weekends for new releases.
