AOL must have been drooling when it realized Warner Bros. had a computer-hacking movie hitting theaters called “Swordfish.”

In a technology-based Internet marketing campaign that makes every Internet geek proud, Warner Bros. has launched an online contest at www.operationswordfish.com that challenges fans to test their decoding skills by attempting to crack their way into the site’s many levels for a chance to win a GMC Yukon Denali, $25,000 in cash, a Dell Inspiron laptop and other prizes.

The “Swordfish” Web site, which launched in March, requires visitors to find and enter 10 specific passwords and 10 keycodes, that once entered, reveal video, photos, outtakes and CGI visualizations from the film and sample music from the pic’s soundtrack, as well as enter Netizens into a $100,000 sweepstakes.

Passwords are being revealed on trailers, TV and radio spots, magazine ads, billboardsvia wireless Palm Pilots and cell phones, via CueCat scanners at Radio Shack stores, subways and bus shelters, as well as on AOL, the WinAmp MP3 player and by e-mailing John Travolta’s character Gabriel Shear using AOL Instant Messenger. Even pic’s stars John Travolta, Hugh Jackman, Halle Berry and Don Cheadle are expected to slip passwords into conversations during TV appearances. The contest’s final password will appear in the end credits of the film, which bows June 8.
