We all have that one person who has changed the world for us. For Lin-Manuel Miranda, that person is his dad. The Puerto Rican entertainer created a documentary to tell his father's story and it is a love letter to his father.

"Siempre, Luis" is Lin-Manuel Miranda's love letter to his father.

The trailer for the HBO Documentary is a moving testament to the indomitable spirit of Luis Miranda. The Puerto Rican powerhouse helped lead a movement to get Latinos involved in and interested in politics focusing on Puerto Ricans who had left the island.

Lin-Manuel's documentary is a deep dive into the life of the man who raised the creator of "In The Heights" and "Hamilton." Luis was Lin-Manuel's inspiration when playing Alexander Hamilton in his wildly popular and famous musical.

"He's just a relentless motherf*cker," Lin-Manuel says in the documentary.

The documentary takes people on a ride covering decades of Luis' life. The main focus is his political activism and how one man helped create a movement to get Latinos involved in politics. Luis leveraged the hate and pushback against the Latino community as a way to energize and mobilize Latinos to get them involved like never before.

Then, Hurricane Maria devastated Puerto Rico, Luis' home and magical escape. The island endured a direct hit from Hurricane Maria, which knocked out power to millions of Americans for months. Many Puerto Ricans fled the island for the mainland giving them a chance to vote for president in 2020.

“For me, Puerto Rico is this perfect place that all of a sudden doesn’t exist anymore," Luis says through tears in the documentary. "I immediately saw it as my responsibility to rebuild the island.”

He added: “Doing everything we can becomes the job.

“I told him, ‘I don’t want to be a widow. There isn’t another you to replace you,’” Luz Towns-Miranda recalls to the camera about her husband's mission to fix Puerto Rico.

Luis' time talking about his work in Puerto Rico is accompanied by videos images of the "Hamilton" stage being constructed for the show on the island. There are shots of Luis offering aid to people and preparing meals for those impacted by the hurricane.

Luis' activism has grown over the years and he is ready to keep making change.

"Siempre, Luis" is now available on HBO and HBOmax for your viewing pleasure. People have praised the film's insightfulness into one of the Latinos who got his community activated and politically engaged.
