Ice Cube got a chilly reception at the multiplex over the weekend. Stepping in for Vin Diesel in the XXX sequel xXx: State of the Union, the rapper/actor attracted only enough moviegoers to take in $13.7 million for a third-place finish, well behind the new release The Hitchhiker's Guide to the Galaxy ($21.7 million) and last week's No. 1, The Interpreter ($14.2 million). Rounding out the Top Five were The Amityville Horror ($8.1 million) and Sahara ($6 million).
