It's Star Wars day, so remember those less fortunate than yourself — that is, people who have never seen the original Star Wars movie, retroactively titled Episode IV: A New Hope.

Yes, they exist, and in greater numbers than you might think.

To address this problem, Mashable has partnered with Change.org and Lucasfilm to host a special screening Saturday night in San Francisco. Dozens of grown-up newbies will get their first taste of Star Wars. Their friends and family will be capturing their reactions live — and you can follow along.

As with our first newbie-watching-Star-Wars event last year, starring Mashable features writer Christine Erickson, the Twitter account @StarWarsPlot will be tweeting out key moments in the movie as they happen. Friends, family and well-wishers will be tweeting with the hashtag #starwarsnewbies.

The newbies will themselves, we hope, be too enraptured by the film to tweet, but we'll be recording their reactions afterwards with Vines. Check back in, as we post the best Vines and tweets here, starting at 7 p.m. Pacific time.

Join in, follow along and May the Fourth be with you.

That time when Luke was way sadder over losing a friend he'd had for a day than losing his aunt and uncle. #starwarsnewbies — Charlotte Hill (@hill_charlotte) May 5, 2013
