Kennedy Series Main Cast & Character Summary
Below is main cast and character details:
Michael Fassbender as Joe Kennedy Sr.
Michael Fassbender is a famous actor who has been nominated for the Oscar award twice for his roles in 12 Years a Slave and Steve Jobs. Recently, he appeared in The Agency and Black Bag. Now, he has been chosen to play Joseph Kennedy Sr..
Talking to People, Keogh said that Joe Sr. is a very interesting character.
Joseph Kennedy Sr. lived for 81 years and built a powerful family from nothing. He became the first chairman of the Securities and Exchange Commission and also served as the U.S. ambassador to the United Kingdom. He was a very successful businessman who made money from steel, whiskey, and Hollywood films.
Laura Donnelly as Rose Kennedy
Laura Donnelly is well known for her TV roles in Outlander and The Nevers. She also has a strong theater background and has won an Olivier Award and received two Tony Award nominations. In the new project, she will play the Kennedy family’s mother, Rose Kennedy.
According to Keogh, while Joe Kennedy Sr. was very active in his children’s lives, Rose was known as a very strict woman. Being Mrs. Joseph P. Kennedy gave her great power, respect, money, and freedom to live life her own way.
Even though Rose had nine children, Keogh says she was not a warm or caring mother. She did not hug her children often or say things like “I love you” or “Are you okay.” She was firm and emotionally distant.
Nick Robinson as Joe Kennedy Jr.
Nick Robinson is best known for his roles in the movie Love, Simon and TV shows like A Teacher and Maid. He will now play Joseph P. Kennedy Jr., also known as Joe Jr., the first son of the famous Kennedy family.
Keogh explains that many people think John F. Kennedy was always the main son, but that was not true at first. Joe Jr. was actually the most important son in the family.
Joe Jr. was strong, good-looking, and confident. Even though he was not seen as very smart, his family believed in him. His father wanted him to become the future president of the United States. Joe Jr. even took part in the 1940 Democratic National Convention and planned to run for Congress after returning from war.
However, everything changed during World War II. Joe Jr. was serving as a navy pilot when his plane exploded during Operation Aphrodite.
Lydia Peckham as Rosemary Kennedy
Lydia Peckham was recently seen in Kingdom of the Planet of the Apes, Nuremberg, and the MGM+ series Robin Hood. She has now joined Netflix’s Kennedy series to play one of the most complex characters.
She plays Rose Marie Kennedy, later known as Rosemary. Rosemary’s life was difficult from the very beginning. She was born in 1918 during the Spanish flu outbreak. Because the doctor arrived late, a nurse told her mother to delay the birth, which caused serious harm to Rosemary and affected her brain.
As she grew up, Rosemary faced learning and development problems. With special teachers and private schools, she improved in many ways. Still, she struggled with her emotions. When the Kennedy family returned from the U.K. in 1939, her father Joseph Kennedy Sr. feared that Rosemary might damage the family’s political image.
Because of this fear, he made a terrible decision. At just 23 years old, Rosemary was forced to undergo a brain surgery called a lobotomy. The operation made her condition much worse and left her unable to live independently.
Saura Lightfoot-Leon as Kick Kennedy
Saura Lightfoot-Leon won a Special Jury Mention at the Venice Film Festival for her first film Hoard. She was also seen in The Agency and Netflix’s American Primeval. She will now play Kathleen Kennedy, lovingly called “Kick”, in the Kennedy series.
Kick was the second-oldest daughter in the Kennedy family. She was bold, confident, and always tried to keep up with her older brothers. According to Keogh, Kick was very similar to John F. Kennedy. Both had a sharp sense of humor and liked to joke, even in serious situations.
Unlike most of her siblings, Kick did not always follow family rules. A Kennedy biographer once called her “the only rebel in the family.”
When her father Joseph Kennedy Sr. was serving as U.S. ambassador to the U.K., Kick became very popular. She stood out among the quiet English debutantes. During this time, she met and married William Cavendish, also known as Billy. He was a powerful British nobleman but was Protestant, which upset the deeply Catholic Kennedy family.
Kick’s marriage was happy but did not last long. During World War II, Billy was killed by a German sniper in Belgium, just one month after Joe Jr. died in battle.
