Homer is here. Many years in the making, 20th Century Fox’s “The Simpsons Movie” opens day-and-date today in markets around the globe, hoping to mine the fanbase of the animated television series, as well as lure newcomers to the irreverent family franchise. “Simpsons,” playing in 3,922 locations domestically and starring the regular TV cast, has a clear shot at the weekend crown over holdovers “I Now Pronounce You Chuck and Larry” and “Harry Potter and the Order of the Phoenix.” Overseas, “Simpsons” debuts in as many as 7,500 playdates in 71 markets. Stateside, the other wide openers include Warner Bros. and Village Roadshow Pictures’ romantic dramedy “No Reservations,” starring Catherine Zeta-Jones, Aaron Eckhart and Abigail Breslin. Going for the female crowd, Warners will bow the film in 2,425 locations. The Weinstein Co. and MGM open urban comedy “Who’s Your Caddy?” at 1,019. Film marks the inaugural release of Bob Johnson’s Our Stories Films, which has a distribution pact with TWC’s Dimension Films. Days after Lindsay Lohan’s latest brush with the law, TriStar opens Lohan starrer “I Know Who Killed Me” in 1,320 playdates. Film was already low on the radar, but it’s unclear how Lohan’s real-life drama will impact box office.
