NEW YORK Matthew McConaughey will romp through the desert in the April 8 release Sahara with help from Ray-Ban and Jeep, the two tie-in partners for the Paramount film. The movie will get in-store support and a possible sweepstakes from Ray-Ban and TV and print from Chrysler's Jeep brand. Chrysler worked with Paramount on 2003's Lara Croft Tomb Raider: The Cradle of Life to promote its Wrangler Rubicon. Sahara features Jeep Grand Cherokees and the Wrangler Unlimited. Ray-Ban will outfit McConaughey with its Titanium Classic. Co-stars Steve Zahn and Penelope Cruz will sport Predator Shot Extreme shades and New Aviator sunglasses, respectively. Meanwhile, Chrysler also has its 300C sedan and Pacifica in Warner Brothers' The Wrong Element, a thriller starring Harrison Ford.
