It's pretty funny how people have such a hard time believing that Hollywood A-list actors are gay.
Just think back to your high school days and try to remember all the studly cool guys in the Thespian Troupe. Exactly. There weren't any. Incredibly, half of male high school actors are gay, half of college actors are gay, and half of Broadway actors are gay. But once you get into TV and Films, where there's actually money to be made (or lost), suddenly there's hardly any gay actors. Sure, we have a few guys who "come out" like David Hyde Pierce (Niles from Frasier) or Neil Patrick Harris (Doogie Howser) or Ian McKellen (X-Men) but the guys who stand to lose their "leading men" status and the accompanying salaries have MILLIONS of reasons to lie.
But they're married, you say? They're ACTORS for crying out loud! If then can win an Oscar, they sure as hell can pretend to be in love or kiss someone they're not attracted to.
Guys like:
Hugh Jackman

Keanu Reeves

Kevin Spacey

Tom Cruise

John Travolta

Eddie Murphy

Jake Gyllenhaal

As if all of the above haven't set off your gaydar faster than saying Philip Seymour Hoffman.
