Wet T-shirt contests are apparently way overrated. Moviegoers resoundly rejected the much-hyped reality flick The Real Cancun over the weekend. The movie about 16 sex-crazed college students grossed an embarrassing $2.3 million at the box office, bad enough to debut in 10th place. The new murder-mystery Identity fared much better, opening at No. 1 with $17 million and bumping Anger Management to No. 2 ($16 million). Elsewhere, crime caper Confidence bowed at No. 5 with $4.75 million and the Kirk-Michael Douglas drama It Runs in the Family tripped up at No. 9 with $3 million.
