Tom Ford and Brett Ratner are backing the Gay, Lesbian and Straight Education Network's new Think Before You Speak campaign, which aims to combat the use of homophobic language.

In association with the Ad Council and Talenthouse, GLSEN has launched a competition inviting aspiring filmmakers to submit a public service advertisement for the initiative, with entries being judged by Ford and Ratner. The winner will be announced May 24 at GLSEN's annual Respect Awards in LA.
