Fans of Robin Williams's more typical comedies may want to read the fine print on this one. Bobcat Goldthwait's World's Greatest Dad — starring Williams as a high-school poetry teacher who finds fame by forging a suicide note — earned strong reviews after playing Sundance in January, and drew more comparisons to twisted films like Heathers than Mrs. Doubtfire. Magnolia Pictures was nice enough to give Vulture first crack at the film's poster. Dad premieres on cable VOD, Xbox Live, and Amazon VOD on July 24, and hits theaters in selected cities on August 21. Click to see the poster!
