On Monday, legendary film composer James Horner died in a plane crash near Santa Barbara in which he was apparently piloting. Horner, who composed classic films such as Aliens, Avatar, Apollo 13 and Titanic touched millions of people around the world with his unforgettable scores.

Céline Dion, who sang "My Heart Will Go On" co-written by Horner for the movie Titanic, said:

"Rene and I are deeply saddened by the tragic death of James Horner. He will always remain a great composer in our hearts. James played an important part in my career. We will miss him. We offer his family and friends our deepest sympathy."

Fellow composer Alexandre Desplat (The Grand Budapest Hotel) had this to say about Horner:

"It is a tragedy for all composers to hear about James Horner's accident. We have lost one of our most talented and respected colleagues. His music will remain always."

Eight-time Oscar winning composer Alan Menken said:

"I count James Horner among the very best film composers of our generation. His work is stirring, emotionally powerful and broadly evocative. Although we only met on a few occasions, I will always cherish the memory of him and his wonderful work."

Marco Beltrami, composer of the music in 3:10 to Yuma, World War Z and The Hurt Locker:

"James Horner was one of the great film composer legends. I can't help feeling that his passing marks the end of an era."
