Runaway Bride (1999),
The Best Man is a zany comedy about male marital jitters. Three years after being left at the alter, Adam (John Newcombe) still cannot make it through a wedding ceremony without becoming violently ill. His friend and editor Jimmy (John Hines) makes a deal with the struggling cartoonist; he will find a buyer for Adam's comic strip if Adam acts as best man for his wedding. Reluctantly agreeing, Adam follows Jimmy and his bride-to-be (Grace Phillips) to small-town Indiana to attend his nightmare dressed in white. ~ Jonathan Crow, All Movie Guide
