Michael J Fox appeals for help in finding lost guitar played by Marty McFly in Back To The Future

The scene in Back To The Future where Marty McFly grabs a guitar before bursting into a rendition of Chuck Berry's Johnny B Goode is perhaps one of the most iconic in movie history.

However, in 2025 the guitar's creators might be wishing they had time-travelling capabilities of their own as the location of the Cherry Red Gibson ES-345 is a mystery 40 years after the film's release. Gibson, based in Nashville, Texas, is asking for helping tracking down the instrument as the company produces a new documentary about the search called Lost To The Future.

Filmmakers had gone looking for the instrument while making the movie's 1989 sequel but it was nowhere to be found. In a trailer shared on X, stars from the movie including Michael J Fox, who played Marty McFly, and Christopher Lloyd who played Doc Brown, have appealed to viewers to help try to find the guitar.

Lloyd, in the cadence of eccentric inventor Doc Brown, says in the video that the guitar has been "lost to the future". "It's somewhere lost in the space-time continuum," says Fox.

"Or it's in some Teamster's garage." Harry Waters Jr, who played Marvin Berry in the film, says the instrument was last seen in 1985.

The time-traveller refers to it is an "oldie where I come from" as the 1958 song doesn't yet exist for his audience. The students at the dance fall into an awkward silence as McFly's riffs turn increasingly wild.

"I guess you guys aren't ready for that yet," McFly says. "But your kids are gonna love it.".
