Born in New York and raised in Florida, Reubens began acting at an early age.

After college, while at The Groundlings Theatre & School in Los Angeles, he created the famous Pee-wee character, with his set premiering in 1981. He later performed at The Roxy on the Sunset Strip.

By 1981, the show had been moved to HBO, with Reubens amassing an even greater following nationwide.

Due to 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.

"Pee-wee's Playhouse" on CBS began in 1986, and accrued 22 Emmy Awards during its five-year run on television. He was personally nominated for 14 Emmy Awards – he won 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.
