On September 6, 1967, in the midst of a pressure-filled six-week pennant race, the Red Sox, Tigers, Twins and White Sox stood together atop the American League. Never before or since have four teams tied for the lead in baseball's final month. On three subsequent occasions including the season's final day, three of them tied again. In 1967 the stakes were high because there were no playoffs. The pennant winner went directly to the World Series. The size, consistent tightness and duration of this pennant race make it unique. Here, for the first time, all four teams and their players are treated equally. The teams provide wonderful contrasts with substantial differences in skill sets, leadership and temperament. Overt psychological and physical intimidation played a major role throughout the season. The standings were volatile, and so were emotions. The stress of competing against so many other teams for so long was constant. Its effects on players, managers and teams were visibly corrosive in some cases and galvanizing in others. Tragically, some wilted or broke. Others responded heroically.

All three films in the psychological sci-fi thriller franchise. In 'The Butterfly Effect (2004), Ashton Kutcher stars as Evan Treborn, a young man who, from an early age, has struggled with his disturbing childhood memories. As a boy, Evan was encouraged by a psychologist to keep a journal detailing the events of his day-to-day life, and now, as a young adult, he revisits these journals to figure out the truth about events that ended in tragedy for his childhood friends Lenny (Elden Henson) and Tommy (William Lee Scott), and the childhood sweetheart Kayleigh (Amy Smart) with whom he is still in love. After making the incredible discovery that he can use the notebooks as a vehicle enabling him to journey back into the past so that his adult mind occupies the body of his childhood self, he begins a series of attempts to redirect history with the aim of saving his friends and loved ones from the traumas that have befallen them. But every time Evan changes something in the past, however small, he finds when he returns to the present that his actions have had unexpected and disastrous consequences. In the action-packed sequel, Nick (Eric Lively) and Julie (Erica Durance) are deeply in love, but when Julie dies in a tragic car accident, Nick isn't willing to say goodbye to his soulmate without a fight. Soon discovering that he has the ability to travel into the past to a point before the time of Julie's untimely death, Nick struggles to find a means of saving his one true love despite the increasingly troubling results that his well-intended heroics seem to have on the future. Finally, in 'The Butterfly Effect 3' (2009), Sam Reide (Chris Carmack) has the ability to jump through time, helping police to identify killers. But after agreeing to help an old friend track down her sister's murderer, Sam breaks his golden rule of non-interference with history, and consequently discovers that his actions have created a terrifying serial killer. As the grizzly headcount rises with each passing day, it's now up to Sam to revisit the past in an effort to identify the murderer before he strikes again.
