Film and TV star Alec Baldwin has spoken publicly about the anti-gay political views of his younger and less well-known brother Stephen.

Stephen is best-known for his roles in the controversial 1994 film Threesome and 1995 thriller The Usual Suspects.

He became a born-again Christian after the attacks on New York on September 11th 2001.

During an appearance on the Howard Stern radio show in January he spoke out about same-sex marriage.

“I don’t believe that gay marriage is in line with God’s Word, which is found in the Bible,” Baldwin said.

“So, what I think doesn’t matter; what I believe is what’s in the Bible and the Bible says that gay marriage is not acceptable.”

His hard line stance contrasts sharply with his more famous brother Alec Baldwin.

The Academy Award-nominated star is an outspoken liberal who had previously threatened to leave the US if George W Bush was elected President.

He is presently enjoying commercial and critical acclaim for his portrayal of Jack Donaghy in the hit TV comedy 30 Rock.

In a recent interview with gay magazine The Advocate Alec seemed unconcerned about his youngest brother’s views.

“In the modern political world, people like that, whether or not I’m related to them, only help us raise money,” he said.

“They want to ban gay marriage because those people are incapable of having a biological family, that’s their only argument.

“You can ban gay marriage, but if you’re going to make it fair, then you have to ban marriage for everybody else who won’t produce children.

“But they just single out groups of people that they hate.”
