Kelsey Grammer’s Historic Battles for America

In ‘Historic Battles for America,’ award-winning actor Kelsey Grammar takes a deep dive into eight key battles that left an indelible mark on this nation. In his hosting duties for Fox Nation, the well-known "Cheers" and "Frasier" actor will take viewers on an inside look at pivotal battles spanning the American Revolution, the Texas Revolution, the Civil War, and the American Indian Wars.

From Bunker Hill to Brooklyn, the Alamo to Antietam, the eight-part series will reveal the tactics and strategies that led to victory or defeat, the motivations and emotions of the soldiers and officers who fought it, the decisions and conditions that led to battle, and the long-term consequences that resonate long after the last shot was fired.

Grammer will serve as a guide for the audience during each close look at the turning point battles.

"I am excited this show will provide the opportunity to share a historical look into some of the most important battles fought through American history, to remember those who fought them, and how they shaped our country," Grammer said of the new series.

Scandalous: Princess Diana

The events surrounding beloved Diana, Princess of Wales' tragic and untimely death in 1997 have continued to confound the world. But, as new details emerge — with an Academy Award-nominated film on the Spencer family descendant making headlines this year to boot --- it would appear her life before her death was just as scintillating.

Scandals followed Princess Diana throughout her short life, especially her highly-publicized marriage and subsequent divorce to Prince Charles. And, although official investigations have concluded the princess died in a tragic accident on August 31 almost 25 years ago, unanswered questions and conspiracy theories still abound.

When news broke, the world was in shock that Diana, Princess of Wales, was killed in a horrific car accident. The public – and the police – first focused their outrage on the photographers, who had hunted Diana like a lion stalking its prey. 

But the first and most forceful accusations came from a grieving father, Mohammed al-Fayed. He was convinced Britain’s spy agency was carrying out an assassination plot to prevent the princess from marrying his son, a Muslim, and having his child.

Prince Charles and Diana Spencer first met in 1977, after he was previously in a relationship with her sister, Sarah.

Investigations would conclude the car wreck was a tragic accident – but no amount of official reports would satisfy the critics who still to this day feel there are too many unanswered questions. Questions about how much alcohol the driver of the Mercedes really had in his system, if a mystery car caused the accident and drove away, or whether British and American security were trying to stop the announcement of a forthcoming engagement of the couple. 

PRINCESS DIANA’S VOICE COACH SAYS LATE ROYAL WAS EXCITED FOR THE FUTURE BEFORE HER DEATH: ‘SHE FELT LIBERATED’

To some, the conspiracy theories weren’t so far-fetched because Diana prophesized her death in letters she left to her trusted butler, Paul Burrell. Just when she was finding love, her life was taken from her.

Now, ‘Scandalous: Princess Diana’ offers a three-part look into her mysterious life and death for royal family enthusiasts to binge.

Mother's Day Murder: A Nancy Grace Investigation

May is often synonymous with Mother's Day. But, as former prosecutor and crime expert Nancy Grace explores, one pair of daughters wasn't able to celebrate with their mom after she'd gone missing on Mother's Day of 2020.

A spy pen, tranquilizer dart, and chipmunk alibi emerge in the search for still-missing Colorado mom Suzanne Morphew. Her husband of 25 years was ultimately charged with murder and then, just last week, the bombshell case was dropped. 

BARRY MORPHEW 'HUNTED AND CONTROLLED' WIFE SUZANNE LIKE AN ANIMAL, INVESTIGATORS SAY

Now, Nancy Grace investigates the Rocky Mountain scene with experts and locals, hoping to get to the bottom of what really happened to Suzanne Morphew on that fateful Mother's Day.
