Blake Shelton has covered Bob Dylan's heart string-tugging "Forever Young" for an emotionally charged new movie called Max, and now a video featuring clips from the film has been released.

The film tells the story of a military dog named Max who is traumatized when his handler/best friend is killed in Afghanistan. Max comes back to the U.S. to live with his handler's family, but the transition is a rocky one.

Shelton's version of the classic song sticks to Dylan's original intent — a blessing from parent to child in the form of a song, wishing them a lifetime of happiness, good luck and the courage to do the right thing. With Shelton's strong, steady voice, the list of wishes almost sounds like a prayer, especially when heard against the backdrop of a flag-draped casket: "May God bless and keep you always / May your wishes all come true / May you always do for others / And let others do for you."

But while Dylan paired his lyrics with a country-rock leaning sound, Shelton's cover is backed by silky-smooth strings, piano and eventually a full orchestra, adding to the song's emotional heft.

The film won't be all sad, though. As the family and the dog both grieve their loss, Max forms a new bond with the soldier's younger brother, and they both help each other heal.

Starring Josh Wiggins as the younger brother, Thomas Haden Church (Sideways, Spiderman 3) and Lauren Graham (Gilmore Girls, Parenthood), Max is set for a July 26 release.

Shelton is currently on tour, with a string of festival and fair dates scheduled through August.
