Diminished Capacity is a comedy film directed by Terry Kinney and starring Matthew Broderick, Virginia Madsen, and Alan Alda. It was released at the 2008 Sundance Film Festival and opened in theaters in July 2008. It was produced by Plum Pictures.
A man (Broderick) suffering from memory loss takes a trip to a memorabilia expo with his Alzheimer's-impaired relative (Alda) and his high school flame (Madsen), where the trio plans to finalize their scheme to sell a rare baseball card.
The movie opened to generally mediocre reviews, with just 33% of critics followed by Rotten Tomatoes giving it a favorable review. USA Today said that it "has moments of sweetness, but not enough poignancy or wit to turn it into the endearing art-house comedy that it aspires to be." Time Out New York said, "Great, just what we needed: another rote exercise in indie-feely humanism."
