Chris Klein feared he had upset a Hollywood executive after his self-confessed "dreadful" "Mamma Mia!" audition was leaked online.
The star was left red-faced after video footage of him singing off-key while trying for a role in the ABBA movie musical emerged on the internet in 2010.
The clip went viral and racked up millions of viewers - and Klein admits he was worried the leak was actually a former colleague's idea of revenge.
He recalls, "I thought to myself, 'Wow, did I p**s somebody off?' Or maybe it was too good of an opportunity to pass up...
"It's a horrible audition. And I took a chance - I can't sing! I don't know why I was in there. But I took a chance! It's a musical - let's see if I can give it a shot. It was really a dreadful audition... What a terrible thing!"
But Klein admits he's finally come to terms with his embarrassing screen test hitting the web, adding, "I thought, 'Oh my gosh, how many horrible auditions have I had? Thousands.' The audition process is such a hoot anyway. And, listen, I'm not going to be great all of the time."
