Johnny Depp remained humble as he accepted an acting award at the Austin Film Festival in Texas on Saturday, insisting he has built his career on "20 years of failures."

The Hollywood star accepted the event's inaugural Extraordinary Contribution to Film - Acting prize at a glitzy ceremony, and he told the crowd of his surprise at his extraordinary success.

He said, "I've built a career on 20 years of failures."

At the event, Depp also handed out a prize to screenwriter Caroline Thompson, his longtime friend who wrote the script for his 1990 movie Edward Scissorhands, while Bones star David Boreanaz was on hand to give an award to the show's writer Hart Hanson.

 Depp concluded the day by putting on a musical set for guests later that evening.
