“Gray Matters” opens with the feel and the tone of a 1930s Preston Sturges screwball comedy with the elegance of a Fred Astaire and Ginger Rodgers duet. Gray (Heather Graham) and Sam (Thomas Cavanaugh) are Manhattan dwelling brother and sister who share similar interests in the arts and entertainment. One day, the brother proposes to Charlie (Bridget Moynahan) and Gray develops surprising and contradictory feelings.
On the Eve of a Las Vegas style wedding, Gray and Charlie share a bath and, after a drunken night of karaoke, a kiss. During the chapel weeding on the Vegas strip, a new love triangle is developed between the newlyweds and the maid of honor.
The Romance narrative follows the predictable narrative structure of the romance movies from the 1930s though the 1990s. Like the Kevin Kline comedy from 1997, “In & Out,” it is the variable of character motivations that makes “Gray Matters” unpredictable.
