The man Johnny Depp helped release from Arkansas' death row has become like a brother to him, right down to getting matching tattoos.

"We have some," Depp said Saturday as he touched a tattoo on the right side of his chest.

"This one Damien designed. It's one of my all-time favorites, and it means quite a lot to me," Depp told The Associated Press before the premiere of the documentary, "West of Memphis," about Damien Echols and his two co-defendants.

Echols said whenever he and Depp get together, they often end up in a tattoo parlor. Depp said it's about "celebrating the moment."

Echols, Jessie Misskelley, and Jason Baldwin spent 18 years in prison for the 1993 murders of three 8-year old boys in West Memphis. All three were released after agreeing to an Alford plea that allowed them to maintain their innocence while pleading guilty.

The three were the subjects of the "Paradise Lost" documentaries, which captured Depp's interest in the case.
