America experienced a collective bad hair weekend as moviegoers flocked to Barbershop in droves. The new Ice Cube comedy debuted atop the box office with $21 million. My Big Fat Greek Wedding held strong at No. 2 with $11 million — bringing its five-month total to $110.7 million. Coming in at No. 3 was Robin Williams's psycho thriller One Hour Photo, which expanded to wide release and grossed $7.7 million. Tom Green's poorly-reviewed comedy Stealing Harvard opened at No. 4 with $6.3 million, followed by last week's No. 1 flick Swimfan (No. 5 with $6.1 million).
