It may have seemed like an "off" week by summer standards in terms of releases, but two debuts and two strong holdovers meant that four films grossed $20 million or more, which is rare for a non-holiday weekend. The top dog, surprisingly, turned out to be The Proposal, which rode a genial marketing campaign and a set of sneak previews to $34 million dollars -- Sandra Bullock's best opening weekend ever, by far.
