If you're going to see one movie about Whitey Bulger this summer, attorney Hank Brennan, who defended James "Whitey" Bulger at his racketeering trial last year, says it shouldn't be "Black Mass," which stars Johnny Depp. Bulger's lawyer endorses Joe Berlinger's documentary, "Whitey: United States of America v. James J. Bulger," which was just released in theaters this week.

James "Whitey" Bulger was arrested on June 22, 2011 after 17 years on the run. Bulger allegedly paid the FBI to look the other way while he took over Boston. Bulger was sentenced to two life sentences and five years behind bars.

Hank Brennan, the lawyer who defended Bulger at last year's racketeering trial, denounced "Black Mass," the big-budget film starring Johnny Depp, as fiction.

Brennan, who is working on Bulger's appeal said "If I ever had a comment about the Johnny Depp movie, I would denounce it as fiction," Brennan told UPI in a recent phone interview when asked if he or Bulger are participating in the making of Black Mass. I think the Johnny Depp movie does a disservice, not only to the public, but it does a disservice to the victims' families."

Brennan isn't against a dramatic movie about Whitey Bulger, but "I think it is so unfortunate that Hollywood has decided to produce a movie with Johnny Depp based on the book Black Mass. ...(which) was written in the year 2000 ... by authors who previously wrote a book called The Underboss where they glorified [FBI] agents like John Connolly and John Morris, who we now know were corrupt and involved in cases of murder."

Brennan says he would prefer to see Hollywood make a version that tells the story responsibly.

"Hopefully, somebody else like [Boston actor-writer-producer] Matt Damon or somebody has a genuine film," he said. "It just has to be truthful."

"A film like Black Mass ignores what we learned in the congressional hearings about the systemic [government] corruption," Brennan continued. "It ignores the 19 trials where we see these families fighting to show that the government was responsible for the loss of their loved ones."

Whitey: United States of America v. James J. Bulger can be seen in theaters in New York and Los Angele and online at video-on-demand platforms.
