ST. LOUIS, MO (KTVI) – A lot of people are rooting for the Chicago Cubs because of a prediction made in the movie ‘Back to the Future II.’ The 2015 World Series Sweep by the Chicago Cubs in the film is a critical plot point. It gives Marty McFly the idea to go back in time to become rich from betting on sports.

During the movie McFly sees 3D news flash during a trip to downtown Hill Valley, California. He is visiting from the from the year 1985.

Marty sees the sign that says, “Cubs win World Series; Sweep Miami.”

“Yeah, it’s something, huh? Who would have thought? 100-1 shot! I wish I could go back to the beginning of the season, put some money on the Cubs.” said Terry.

Marty McFly, “I just meant that Miami- What did you just say?”

“I said I wish I could go back to the beginning of the season, put some money on the Cubbies!” said Terry.

Marty ends up buying Gray’s Sports Almanac. He puts it in the time machine with a plan to use it in 1985. That is before the series’ villain Biff Tannon steals the idea and ends up making a mess out of history.

The scene deserves some scrutiny.

There wasn’t a team in Miami in 1985. This would have been a surprise to Marty McFly. The Marlins came to town in 1993 and are in the National League. They would never meet the Cubs in the World Series, especially with this year’s record.

An extra round of playoffs and a wildcard game mean much longer MLB post-seasons. In the movie the Cubs clinch on October 22, 2015. This year’s World Series won’t even start until at least October 27th.

The Hill Valley USA Today says, “Cubs Sweep Series in 5.” That would suggest a best of nine game World Series. The series is still best of seven.

In the clip Terry says the Cubs were a 100-1 shot. That is also not true. Pre-season odds for the Cubbies in Las Vegas were as short as 6-1.
