This year is the 50th anniversary of the show's premiere, and on Tuesday Rogers-who died of stomach cancer in 2003 at the age of 74-would have turned 90. The documentary chronicles how the unlikely star became a household name and most beloved children's show host through his groundbreaking children's show Mister Rogers' Neighborhood.
"If you take all the elements that make good television and do the exact opposite, you have "Mr. Rogers" Neighborhood,"' producer Margy Whitmer says in the clip.
The episodes start streaming at 1 p.m. ET on March 20. There hadn't been anything like Mr. Rogers on television before and there hasn't been since.
"The Fred Rogers I discovered making this film is at once comfortably familiar and completely surprising".
"Mister Rogers always managed to find wonder in seemingly everyday things, turning visits to factories, farms and museums into engaging and educational journeys", the USPS continued.
"A little boy came up to him and said, 'Mr". Clemmons would be the first African American in a recurring role on a children's television program.
Rogers also testified in front of the U.S. Senate for more federal funding for children's television, reflecting his belief that kids need programming beyond slapstick cartoons.
The documentary, which will hit theaters on June 8, will likely be praised for its message of hope and caring amid the unrelenting negativity and divisiveness coming from Washington.
"I've always felt that I didn't need to put on a amusing hat, or jump through a hoop to have a relationship with a child", Rogers says in the trailer.
