Riding the wave of intense Internet buzz, Sony Picture's sci-fi flick District 9 is expected to prevail over four other newcomers this weekend as well as last week's champ, Paramount's G.I. Joe . The film tells the story of aliens from outerspace who become reFugees in South Africa. Likewise, in the romance domain, Warner Bros./New Line's The Time Traveler's Wife is expected to prevail over last week's No. 2 film, Julie & Julia. Three other films that are opening wide target other sectors of the audience. There's Disney's English-language version of the worldwide animated hit Ponyo from legendary Japanese animator Hayao Miyazaki. There's the teen musical Bandslam from Summit Entertainment and Walden Media, and there's the Jerry Piven comedy The Goods Live Hard, Sell Hard, from Paramount Vantage. The latter three are expected to earn less than $9-12 million . District 9 is expected to come in at around $25-30 million, while The Time Traveler's Wife is likely to earn $15-20 million, according to box-office forecasters.
