Before 'Buffy the Vampire Slayer' became a TV series watched by every household under the sun, it was first a movie of the same name.

Released in cinemas in 1992, 'Buffy the Vampire Slayer' saw Buffy Summers played by Kristy Swanson, and featured relatively unknown actors who went on to make the big-time - including Hilary Swank, Luke Perry, and David Arquette. Joss Whedon, who went on to create the TV series of the same name, was a writer on the project. However, the biggest one of all to make it from the movie was Ben Affleck. Although he probably wishes his role in the movie wasn't so well-known.

In a recent interview on a radio show in America, he spoke about having one single line in the movie, as he played a basketball player who witnesses someone begin to turn into a werewolf. He told the radio hosts: "Apparently, I'm so bad in that movie. I had one line. It was 'Take it,' I think."

He thought that he had done a good job of saying the line, and said that director Fran Rubel Kuzui seemed happy too. Sadly, when Affleck went to go and see himself on the big screen in the cinema, he discovered that it wasn't actually him who said his line. Awkward.

"I went to the movie and I was like, 'That is not my voice. That is not me'. Apparently the director hated my performance so much that she looped the entire performance, which was one line. So, yes, I am dubbed — in English!"

Luckily for him, he didn't let his one bad role deter him from being the well-known actor that he is today.

Here's Affleck talking about his unfortunate discovery.

Ben Affleck is currently doing the rounds for his upcoming movie 'The Way Back' which will be released in Irish cinemas on April 24th.
