Here's a sure-fire holiday hangover cure for you science fiction fans: GLAAD has announced that the latest PSA in their "Be an Ally & a Friend" campaign featuring towel-ready Battlestar Galactica hunk Jamie Bamber will premiere on the net immediately following the highly-anticipated Battlestar Galactica: Razor miniseries this Saturday.

This is great news on a number of levels. One, the miniseries is one of the hottest tickets of the TV season and the placement of a 20-second message of understanding from Bamber (along with Ugly Betty's Eric Mabius, Brothers & Sisters' Jason Lewis, and Carpoolers' Jerry O'Connell) is prime. And two, given how many gay fans Bamber has made (he ranked an impressive #25 in the AfterElton Hot 100), it's great to see him speaking out in this campaign.

For previous PSAs from the campaign, head on over here.

Former NBA player and out athlete John Amaechi is the star of a new public service announcement from GLAAD. The PSA, which was released yesterday to coincide with the start of the NBA's 2007-2008 season, is the fifth installment of GLAAD's "Be an Ally, Be a Friend" public education campaign.

In a press release announcing the new ad, GLAAD Director of Sports Media Ted Rybka said:

"John has experienced firsthand how homophobia in the sports world can prevent athletes from living their lives honestly and openly. [His] message has the power to awaken people to the realities of what it's like to be a lesbian, gay, bisexual or transgender athlete."

The campaign began in September and features twenty-two entertainers from the world of film, television, and sports imploring viewers to take a stand against homophobia by acting as an ally to gay, lesbian, bisexual, and transgender people. The previous ad, starring T.R. Knight, was released in honor of National Coming Out Day.

It's great to see recently out figures like Knight and Amaechi use their celebrity to advocate for LGBT rights. It's something that Amaechi seems to care strongly about, as he mentioned when we interviewed him after he came out in back February of this year, making him the first NBA player ever to do so.

You can watch Amaechi's PSA after the break.

GLAAD will be launching a series of new public service announcements starting today. They are a part of an ongoing campaign called “Be an Ally and a Friend” and feature a number of gay or gay-friendly celebrities asking straight people to be “allies” of the gay community.

The list of talent recruited for this campaign is pretty impressive. It includes the likes of Rachel Griffiths (Brothers & Sisters), Michael Urie (Ugly Betty), T.R. Knight, Sara Ramirez and Kate Walsh (Grey’s Anatomy). What, no Isaiah Washington? Didn’t he tape a PSA for GLAAD awhile back? I guess his segment didn't quite make the cut.

No matter. You can view the first of the new crop of PSA’s on GLAAD’s website. That one includes Jerry O’Connell, T.R. Knight, Marlee Matlin, and John Amaechi. Coming in the next few weeks is PSA from the cast of Ugly Betty.

Of note: One of the first “Be An Ally and a Friend” PSAs (from back in 2006) featured As The World Turns actors Van Hansis (Luke Snyder) and Martha Byrne (Lily). You can watch their PSA here.
