Hollywood star Bradley Cooper says he was worried his directorial debut ‘A Star Is Born’ would “fail miserably”.

“I was just hoping that I wouldn’t fail miserably. It’s vulnerable, you know, writing, co-writing, telling a story and directing it. I mean I had no idea what was going to happen,” Cooper told etonline.com.

“I just knew that I had to try. So, the fact that it has been well received, I just want savour it,” he added.

Cooper teamed up with pop star Lady Gaga for the film.

He said he would be keen to turn the film into a Broadway show.

Asked about the possibility, he said: “Yeah, that would be a great idea. I mean, we have the music!”
