From The AP:
Takei said his new onstage role as psychologist Martin Dysart in "Equus," helped inspire him to publicly discuss his sexuality.
Takei described the character as a "very contained but turbulently frustrated man." The play opened Wednesday at the David Henry Hwang Theater in Los Angeles, the same day that Frontiers magazine featured a story on Takei's coming out.
The current social and political climate also motivated Takei's disclosure, he said.
"The world has changed from when I was a young teen feeling ashamed for being gay," he said. "The issue of gay marriage is now a political issue. That would have been unthinkable when I was young."
The 68-year-old actor said he and his partner, Brad Altman, have been together for 18 years.
