The movie star admits the note from his old friend meant as much to him as winning accolades for the film.
He recalls, "Coming from her, it was very special and it was very generous and heartfelt letter. It brought me to tears, really."
The pair reunited for the first time in 23 years on the red carpet at the premiere for their new movie The Informers in Hollywood on Thursday, and Rourke admits he was very nervous about meeting the screen beauty again.
He says, "We had no screen time together in the movie (The Informers), so I was very nervous. I hadn’t seen her in 23 years."
