A biopic of troubled British singer-songwriter Amy Winehouse tracking her meteoric rise and very public downfall opens in U.K. cinemas today amid a swirl of controversy.

Even before its release, "Back to Black" has attracted backlash with criticism ranging from the casting to concerns it could exploit Winehouse's story.

The dress singer Amy Winehouse wore for her final performance sold on Nov. 7 for $243,200, 16 times its estimated value, as part of a trove of memorabilia from the late diva's life auctioned in California.

Winehouse wore the green and black bamboo print dress at a concert in Belgrade in 2011.

A month later, on July 23, she died from acute alcohol poisoning. She was 27.
