Michael J. Fox and Christopher Lloyd Designed A 'Back to the Future' Merchandise Collection

Great Scott! Marty McFly and Doc Brown are back! And they brought T-shirts!

Well, not technically Marty and Doc Brown, but the real-life duo of Michael J. Fox and Christopher Lloyd just announced the debut of a new "Back to the Future" merchandise line, which the two helped design for fans of the beloved sci-fi trilogy.

It's the first official line of "Back to the Future" merchandise, according to Yahoo, and Fox said that by using lines and references to the movies, the shirts are a labor of love to the fans.

"We kept hearing they wanted more options to celebrate 'Back to the Future' devotion, and we thought these items were perfect for it," Fox says in a quote on the store's webpage. "Enjoy it. Heavy."

From now until Dec. 10, fans can buy T-shirts, a red vest like the one Marty wore in the film, and hats. Designs feature references to Marty's famous guitar solo at the "Enchantment Under the Sea" dance, the Delorean's "OUTATIME" license plate," 1.21 gigawatts (the necessary amount of energy to power the Delorean back to 1985), and the movie's poster.

This collaboration is for the fans! We wanted to celebrate you all with this limited edition merchandise collection. See the full collection of designs and signed collectibles at the link in my bio or go to https://t.co/fkq2LqNJFM pic.twitter.com/Ox0ba2ZdkS

There are also special autographed items, like a framed poster signed by both Fox and Lloyd.

Proceeds from the collection will benefit the Michael J. Fox Foundation, which raises money for Parkinson's disease research and therapies.
