Matt Damon and Greg Kinnear make a terrific team in this delightfully demented comedy about twin brothers who share a passion for life - and a liver. Thanks to great teamwork their physical condition is no handicap. But now the clash between Walt's big dreams of stardom and Bob's extreme shyness is tearing these conjoined twins apart. From the pursuit of acting roles to dating a pair of lovely ladies, they somehow keep getting in each other's way. When the inseparable duo face outrageous obstacles in Hollywood and meet an incredible cast of characters, including Eva Mendes and Cher, the results are hilarious.
