The young Ben Affleck only had two words to say in the Buffy The Vampire Slayer movie, way back in 1992.
But he delivered them so badly, that the director had them dubbed over by another actor.
This was all some years before Joss Whedon would take over the reigns to make his now iconic spin-off TV series, and found Fran Rubel Kuzui behind the camera.
Kristy Swanson played the title role of the cheerleader turned vampire killer, with Luke Perry playing Pike and other roles for Donald Sutherland, Rutger Hauer, Paul Reubens and Hilary Swank.
Affleck, meanwhile, was uncredited as 'Basketball Player #10'.
Speaking in an interview for the Jess Cagle Show on SiriusXM, he said: “Apparently, I'm so bad in that movie. I had one line.
“I'm holding a basketball, and another basketball player turns into like a werewolf or whatever, and I get scared, naturally, as you might if you saw a werewolf playing basketball, and I give him the ball and I think I say 'take it, man'.
“I thought it was fine, and the director seemed happy, and I went to the movie – I didn't get premiere tickets or anything – 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. So yes, I am dubbed. In English! Usually you do that if they're speaking a different language.”
It was perhaps for the best.
The movie was savaged by critics, and bombed disastrously at the box office, only for Whedon to pick up the concept five years later, install Sarah Michelle Gellar and create a cult classic TV show which would span seven seasons and 144 episodes.
Ben Affleck ended up doing OK too.
In the same year that Whedon's Buffy series landed on The WB network in the US, Affleck, with his pal Matt Damon, released Good Will Hunting and won an Oscar for Best Original Screenplay at the 70th Academy Awards.
