Miramax and Dimension will release nine films in August and September, including such high-profile movies as “Proof,” “An Unfinished Life” and “The Brothers Grimm.” While that makes for a crowded schedule, it allows the Weinstein brothers to oversee the marketing and distribution before they leave. Miramax’s crowded late-summer schedule now calls for the wide release of “Underclassman” and limited debut of “Secuestro” on Aug. 5, followed by the wide release of “The Great Raid” on Aug. 12. On Aug. 26, Dimension’s “The Brothers Grimm” goes out wide. On Sept. 9, the label has set two limited releases, “An Unfinished Life” and “Curandero.” A week later come “Proof,” “The Libertine” and “The Reaper,” the latter in wide release. Release dates are never written in stone, and some industry observers doubt all nine titles will find releases on these days.
