The starry 8 PM reading — which will benefit Testimony, a project of the Courage Campaign Institute — will boast the talents of the previously reported Alan Cumming, John Glover, Luke MacFarlane and Jason Ritter. Michael Morris directs.

Newly announced for the evening are Matt Gould, David Alan Grier, Justin Kirk and Jeffrey Tambor.

Some Men, according to press notes, "chronicles the lives of gay men in the United States over the past 80 years, examining the challenges, the victories, the joys and the sorrows of this history through the prism of love and marriage."

Some Men played Manhattan's Second Stage Theatre in 2007 with a cast that included Don Amendolia, Michael McElroy and Frederick Weller.

Dan Bucatinsky, Susan Dietz and Tom Kirdahy are producing the benefit.

Testimony is designed to "bring the Prop 8 trial into the lives of Americans and empower them - gay and straight - to share their stories and change the way America thinks about LGBT rights."

Tickets, priced $25-$250, are available by visiting TicketMaster: http://tinyurl.com/2b3743w. The $250 tickets include a post-performance, onstage reception with the cast and producers. Those unable to attend the reading on Oct. 4 can make a contribution to support the campaign's marriage equality work by visiting www.couragecampaign.org.

The Saban Theatre is located at 8440 Wilshire Boulevard in Beverly Hills.
