The composer died in a plane crash last month, with the Jake Gyllenhaal boxing film serving as one of his last scores.

Composer James Horner left a handful of film scores completed when he died in a plane crash last month.

One of the first of those final compositions is the score for the Jake Gyllenhaal boxing film Southpaw, which hits theaters on Friday.

The Weinstein Company is honoring Horner with a card at the end of the movie that reads, "In Memory of James Horner."

Shortly after Horner's death, Southpaw director Antoine Fuqua said of the composer, "He was a legend, an artist and a great friend…He was magical to work with, and I feel blessed that we had the opportunity to collaborate together."

In addition to Southpaw, Horner also did the music for Chilean miner drama, The 33, set to hit theaters in November, and he secretly completed the music for Fuqua's upcoming Magnificent Seven remake, the director revealed on NPR.

Fuqua also told NPR that Horner did the Southpaw score for free because he was such a fan of the film.

"He called me on a Saturday, after he watched the movie, and I said, 'I don't have any money' because it wasn't a big budget movie," Fuqua explained. "And he said to me, 'I love the movie. I love the father-daughter relationship. Don't worry about the money. I'm just going to do it.' And he did it for nothing. He paid his crew out of his own pocket."
