Last week the box office outdid itself, with a plethora of blockbusters pushing it up 22 percent over the same weekend a year ago. That's not going to happen this weekend. A year ago, the opening of Warner Bros.' The Dark Knight Rises brought in $160 million. This weekend two movies with $100-million-plus budgets will be making their debut, but analysts aren't forecasting a whole lot of success for them. The Dreamworks Animation/20th Century Fox family film Turbo will likely debut with around $35 million, including about $10 million generated on Wednesday and Thursday. R.I.P.D., starring Ryan Reynolds and Jeff Bridges, is expected to earn less than half that amount. Red 2, starring Bruce Willis, is likely to earn somewhat more -- around $15-18 million, analysts say. Meanwhile, the movie that most box-office pundits figure will come out on top is the one that probably cost the least to produce of any film currently in multiplexes: the supernatural horror flick The Conjuring, which, analysts say, will probably wind up with around $35-40 million.
