Paul Reubens worked with kids with cancer before his death: Holton
"Pee-wee’s Big Adventure" co-star Mark Holton joins "Fox Across America" to reflect on his friendship with the Pee-wee Herman legend after his death.
Paul Reubens' cause of death has been revealed a little more than month after the actor died at age 70 on July 30.
Reubens, who was best known for playing the beloved children's character Pee-wee Herman, died due to acute myelogenous leukemia, his representative confirmed to Fox News Digital.
According to the National Cancer Institute, acute myelogenous leukemia is a "cancer of the blood and bone marrow" and it is the most common form of acute leukemia in adults.

In a personal statement that was shared after his death, Reubens apologized for not revealing his health struggles and expressed his love for his fans.
"Please accept my apology for not going public with what I've been facing the last six years," he wrote in a statement on his social media pages.
He continued, "I have always felt a huge amount of love and respect from my friends, fans and supporters. I have loved you all so much and enjoyed making art for you."
In a separate statement, Reubens requested that any "expressions of sympathy be made in honor of his late parents, Judy and Milton Rubenfeld, to Stand Up to Cancer or organizations involved in dementia and Alzheimer’s care, support and research.
Reubens created the character of Pee-wee Herman after joining the Los Angeles improv troupe The Groundlings in the late 1970s. In 1981, he debuted "The Pee-wee Herman Show" at the Roxy Theater on the Sunset Strip, performing for children at weekly matinées and adults during a midnight show.
"The Pee-wee Herman Show" became a hit and gained an even greater following nationwide when it began airing as a special on HBO.
Due to its success on the small screen, Warner Bros. was interested in taking Pee-wee to the silver screen with the movie that was Tim Burton's directorial debut, "Pee-wee's Big Adventure," in 1985. The film became a box-office success, grossing more than $40 million and gained a cult following. Reubens went on to reprise his role as Pee-wee in the 1988 sequel "Big Top Pee-wee," which was a critical and box-office disappointment.
In 1986, Reubens launched his CBS live-action children's television show "Pee-wee's Playhouse," which ran for five seasons and won 22 Emmy Awards, Reubens himself was nominated for 14 Emmy Awards, winning two.

Circumstances for Reubens changed in 1991 after he was arrested for masturbating in an adult movie theater. He was severely scrutinized and faced repercussions from the arrest.
Although "Playhouse" was already off the air, Toys "R" Us pulled all Pee-wee Herman toys from stores and Disney-MGM Studios pulled his studio tour.
Reubens ended up pleading no contest to the charges, remaining relatively off the radar during the 1990s.

In 2002, he was arrested on charges of possession of pornography. The original charge was for possession of obscene material improperly depicting a child under the age of 18 in sexual conduct, but it was later reduced to a misdemeanor of obscene material.
For three years, the actor had to register his address with the sheriffs' office and was additionally not allowed around children unless given permission by a parent or legal guardian.
