Sean Paul Lockhart is an American actor and director. Lockhart's acting career started in gay pornographic films, using the stage name of Brent Corrigan. He appeared in his first film "Every Poolboy's Dream" (2004) when he was only 17 and featured in another seven films for Cobra Video.

He has been at the center of two major controversies. The first was when he disclosed that he had been underage in his first pornographic video. This led to a second, in which Bryan Phillips (aka Bryan Charles Kocis), of Cobra Video, laid a claim to the screen name "Brent Corrigan", effectively stating that Lockhart would not be able to work in the adult industry under his established screen name and therefore might have difficulty finding work at all. When Lockhart launched a website, BrentCorriganOnline.com, Phillips sued him for copyright infringement, cyber-squatting, and breach of contract for using his screen name. This lawsuit was to go before a judge in February of 2007. Before that, however, Lockhart met two other producers, Harlow Cuadra and Joseph Kerekes of Falcon Films, who expressed interest in working with him, but knew that would be difficult with Phillips staking a claim on his name. In January of 2007, Phillips was found stabbed 28 times, with his throat cut and nearly decapitated. His home was also set on fire to conceal evidence. Cuadra and Kerekes appear to have killed Phillips to get Lockhart out of his contract and legally able to work for other producers under the name "Brent Corrigan". Though his involvement, however indirectly, in a murder could have damaged his career, it has not. Lockhart was never accused of conspiring with Cuadra and Kerekes, and no evidence of such a claim has ever surfaced. Furthermore, when it became clear that he may have been a motivating factor, Lockhart cooperated fully with authorities in helping them find their suspects. Cuadra and Kerekes were both given life sentences.

Lockhart has successfully moved on with his career, having established his own web site, continuing to work in adult films, appearing in some gay-themes mainstream films, and making PSAs for safe sex.

He has appeared in "Milk" (2008), "Judas Kiss" (2011) and "Triple Crossed" (2013).
