This Wednesday may be just another day for a lot of people, but for Back to The Future fans, October 21 marks the day Marty McFly (Michael J. Fox) and Doc Brown (Christopher Lloyd) traveled to the year 2015 in Back to the Future Part II. Universal Pictures Home Entertainment have been heavily promoting the anniversary for months, with the Back to The Future 30th Anniversary Trilogy arriving on Blu-ray & DVD tomorrow, and the entire trilogy returning to theaters on October 21. The studio has also launched an innovative Facebook profile for Doc Brown himself, which is run by a bot that will actually "interact" with fans. Here's Doc's post from earlier today, where he asks for fans' help.

"Doctor Emmett Brown Travel Log Visit to 2015 Day 1: I have traveled back to 2015 and my thought-to-text translator is fully functional. I have been engaged in the scientific pursuit of gathering information from the current inhabitants of 2015. I need additional data, so please message me."

If you want to "help" Doc out, visit his Facebook and click on the Message button on his profile. Once you send a message, this bot/Doc responds shortly thereafter, asking for your help by asking about what the future in 2015 is really like. During my brief "conversation" with Doc Brown, he wasn't too pleased that self-lacing sneakers haven't been invented yet, while inquiring what a Pumpkin Spice Latte is. After Doc runs out of time, a link to Universal Pictures Home Entertainment's Back to the Future Trilogy set appears.

You can keep going back to "speak" with Doc as often as you want, and the conversation will vary slightly each time. With the October 21 date approaching, it seems likely that Doc will keep posting throughout this anniversary event. Over the past few weeks, we've seen a Pepsi Perfect commercial, a "trailer" for Jaws 19 and a video that reunites Michael J. Fox with Christopher Lloyd, with the full video debuting on October 21. Toyota will also unveil their hydrogen fuel cell vehicle dubbed the Mirai, using technology that was predicted in the movie.

Surprisingly, Doc Brown doesn't mention the Chicago Cubs, which is odd since the baseball team is currently playing in the National League Championship Series. If they win, it would send them to the World Series, which Back to the Future Part II actually predicted. As of now, the Cubs are down 2-0 to the New York Mets, so unless they can pull off a comeback, it will be yet another Back to the Future Part II prediction that didn't come true. Visit to interact with Doc Brown yourself. We'll keep you posted throughout the week for more news on the Back to The Future 30th Anniversary celebration.
