Daniel Radcliffe has continued his support for bullied gay youth with a new public service announcement supporting the Trevor Project helpline.

The British actor recorded the video for the California-based organisation which runs a support helpline for gay, bi and trans youth.

He says: “I’m Daniel Radcliffe, and I believe that reaching out for help is the bravest thing a person can do. If you are struggling and need support, call the Trevor Lifeline. It’s free and confidential, and trained counsellors are there to listen 24/7 without judgment.”

The PSA aired this week in the US after an episode of Glee.

In the March issue of Attitude magazine, Radcliffe says: “The ultimate reason gay marriage should be legalized everywhere is because, as a kid, you look to your mum and dad and they’re married; then you look at the gay couple who’ve been together for the same amount of time, but because they can’t get married their relationship doesn’t seem the same.

“Yes, gay marriage is about symbolically blessing a relationship, but the larger issue is about transmitting a fundamental message about equality. Gay people should have equality in law everywhere.”

His Harry Potter co-star Emma Watson recently revealed journalists had been asking whether her short hairstyle and meant she was coming out as a lesbian.
