Springsteen's personal note to Brolin
The Born in the U.S.A. hitmaker makes an appearance on the programme, which features stars like Matt Damon, Morgan Freeman and Don Cheadle speaking about America's struggles with war, race, class and women's rights. The show, which Brolin produces, is based on author Howard Zinn's book A People's History of the United States.
Springsteen, a big fan of Zinn's work, was invited to voice his opinions on the hot topics for the show, but his hectic touring schedule meant the singer almost missed out on the project altogether.
Brolin finally managed to secure a date with Springsteen but was unable to attend the shoot at the superstar's estate - so the rocker decided to send the W. actor a personal message to thank him for setting it all up.
Brolin says, "Everybody (on the film crew) but myself got to go to his farm in New Jersey. I was working, so they all called me on my phone, left a nice message as they were doing it, saying they were having the greatest time.
"But Bruce actually sent me stationery that says 'Bruce Springsteen' on top, that said, 'Josh, thank you for making my childhood dreams come true. All the best, Bruce.'"
