Actor Jason O'Mara was worried about "humiliating" himself as Batman.

The 41-year-old star, who lends his voice to the iconic superhero in animation Son of Batman, had concerns that he might not live up to expectations.

Speaking to, Jason said: A"I just didn't want to mess it up, to be honest with you. It's celebrating 75 years of Batman. We've had so many great actors play it so well, over the years, in film, on television, and through voice work, that I just didn't want to completely humiliate myself."

On perfecting the role, Jason added: "So, when I talked to [voice director] Andrea Romano about how to find this Batman voice, it was really about finding something that was authentic, but also was unique to me. I didn't want to cover ground that had already been covered, so it took awhile.

"It's like writing a song. You do one version and go, 'Oh, that sounds like someone else, or something else.' And then, you do another version and go, 'No, I'm forcing that. I'm pushing that.' And so, you try to come across something where you can go, 'Yeah, that could work.'"
