Are you kidding? Turtle was released against a lot of summer blockbuster movies and ended up playing in only 100 screens. Still it will be very profitable after the DVDs are sold during the Christmas season. With Regal pumping AFIL with previews and in-theater posters it will have tons more publicity and a higher average per screen than Turtle (unless you think Regal is incompetent). It also doesn't have to go up against a ton of blockbusters every week and appeals to a much wider audience than a nature documentary.
