The Immortal Life of Henrietta Lacks film billboards...

The Immortal Life of Henrietta Lacks TV movie adapts Rebecca Skloot's 2010 nonfiction book for the small screen and tells the story of 'Henrietta Lacks', who unbeknownst to her had a tissue sample of the 'immortal' cell line, known as HeLa, harvested from her cervical cancer cells in 1951 that went on to revolutionise biomedical research.

In the adaptation Rose Byrne stars as the journalist (and book author) trying to convince Henrietta's daughter, 'Deborah' (played by Oprah Winfrey), that she can tell the truth of her mother's story, giving her the credit she deserved.

It's amazing to think that this breach of ethics supplied a strain of hardy cells in laboratory conditions, allowing more time for examination, that helped the development of pharmaceutical drugs and treatments to combat the likes of cancer and AIDS.

These HBO TV movie billboards were snapped along La Brea Avenue, Santa Monica Boulevard and Beverly Boulevard from March 29 to April 10, 2017.

Fans of the actress, TV host and businesswoman, can also check out this giant launch billboard for Oprah's Own network billboard from 2011.

Just as with the movie Hidden Figures enlightened people about the contributions of black women to NASA's space program, here's another true story from history how one African-American woman has impacted everyone's lives around the globe.

Meanwhile in light of the timely Bill O'Reilly sexual harassment scandal at Fox News, you can also check out another powerful story from women's history with these Confirmation movie billboards about Anita Hill's historic decision to testify about the sexual harassment she suffered at the hands of her former boss and U.S. Supreme Court nominee Clarence Thomas.

Now back to HBO's most recent film. In the words of Oprah, "You get to watch, and you get to watch and you get to watch" (if you have HBO, that is).

UPDATED: Here's also an Emmy consideration billboard for the 'Exceptional' drama snapped along Santa Monica Boulevard on May 27, 2017.

Plus here's another standard landscape Emmy FYC billboard for the telefilm spotted along La Brea Avenue on June 27, 2017.

UPDATED: Congratulations to the telefilm for scoring an Outstanding Television Movie Emmy nomination. This 'Powerful' nominee billboard was spied along Santa Monica Boulevard on August 26, 2017.

UPDATED: The Immortal Life of Henrietta Lacks may not have won an Emmy, but can the telemovie nab a Golden Globe, SAG Award, or another industry accolade this season? Maybe this FYC billboard snapped above Highland Avenue on December 1, 2017, will help.
