Over 20 years have gone by since My Best Friend’s Wedding came out, but it remains a favorite among fans. This month, cast members from the film grace the cover of Entertainment Weekly’s first rom-com issue while donning stylish wedding attire.

The foursome who starred in the ‘90s era classic are Julia Roberts, Cameron Diaz, Rupert Everett, and Dermot Mulroney dished on some of the things that went on behind-the-scenes, including how Diaz handled her karaoke scene.

Playing rival characters Julianne (Roberts) and Kimmy (Diaz) meant having Roberts be the villain, which is something people weren’t used to seeing from her. The original ending for the movie had her paired with a new love interest played by John Corbett.

Test audiences were not happy with that at all, so they changed it to where Julianne danced the evening away with her gay bestie, George (Everett). As far as the silly yet moving karaoke scene, there was a real set-up with a lyric screen and Diaz sang it the only way she could – naturally.

She told EW.com:

“I was terrified to do that scene, for real. I allowed the true terror of singing in front of people to be alive in me. I wanted to run and hide, and Dermot kept me there. He said, ‘You can do it, you can do it.’ In the scene I’m just staring at him the whole time because he’s looking at me like, ‘You’re okay. You’re not gonna die.’ And I was like, ‘But I’m dying.’”

Everett, who was at first unsure about his role in the movie, learned that his character made a difference in how the story was told. By the time filming wrapped, he grew to appreciate his part:

“But we all got on so well straightaway. And everybody clicked on screen straightaway, and you could feel that. And for me, it was magical. But the last time I saw it, it kind of made me cry just thinking of how magic that time was, that summer.”

Take a peek at the video below to see the original ending where the movie’s scheming character, Julianne, gets a happy finale that audiences didn’t want. Tell us if you prefer this one or the reshoot!
