After coming out last year, Wentworth Miller kept a fairly low profile. But he's back in the upcoming thriller The Loft, about a group of men who find a dead woman in a secret apartment they share for extramarital affairs.

Miller also appears in the August issue of Details, where hediscussed the film, his battle with depression, and the toll that being in the closet took on him.

"At one point I was about 45 pounds heavier than I am now," recalls the 42-year-old actor-writer. "I was looking to food as a fix for something missing inside—it was about putting layers of protection around me."

Coming out, he says, has enabled him to feel "more fully expressed."

After Prison Break, I came to grips with the fact that my public persona was in misalignment with how I actually felt. I was out to a handful of people in my twenties, and once I hit 30, I was out to family and friends.

But professionally, I was feeding a fantasy. I created this air of "We don't address that thing."

He regrets denying he was gay while Prison Break was on, but thinks "audiences knew to a certain degree." He also thinks America can handle gay actors in hetero roles just fine.

"I think it's possible to have a man-crush if you're not gay or to have a crush on a guy you know to be gay if you're a woman," says Miller. "I think our imaginations are strong enough to hold a container for all of this complexity, even if we know on a subconscious level something's not what it appears to be."

Yep, it's called acting.
