This weekend, clay will pay

After two weeks atop the box office chart, Jodie Foster’s Flightplan will certainly be displaced this week. But by whom? Cameron Diaz? Al Pacino? Or a guy and a dog made out of clay?

Bet on the clay. The very first Wallace & Gromit feature, subtitled The Curse of the Were-Rabbit, follows creator Nick Park’s Oscar-winning short films and should satiate the recently underserved family market with its G-rated but smart silliness. Expect a debut in the $20 million range this weekend.

Also opening this weekend: One film for the guys and one for the gals. Cameron Diaz and Toni Collette play sisters in the emotional In Her Shoes, which should draw women (and the men they drag along) to the tune of about $15 million, while Al Pacino and Matthew McConaughey’s sports-gambling drama Two for the Money should kick off with about $12 million.

Flightplan, meanwhile, will see another 40 percent drop to $9 million, while the new restaurant comedy Waiting…, starring Ryan Reynolds, should debut with about $6 million.
