For language geeks like me, accent reduction is a term used to describe losing a foreign or regional accent to adopt a more popular one (e.g., American). It’s an important part of a person’s identity, but sometimes pronunciation that’s hard to understand can lead to miscommunication in professional settings such as business and academia.
In fact, many well-known actors use accent reduction to cast more movie roles. And sometimes even the most attentive film-watchers take them as born and bred United States citizens.
So when redditor Jma7400 asked fellow users who were some actors they couldn’t believe weren’t from the US, over 4000 people shared their eye-opening discoveries. Some of them channel their inner American so well, they deserve all the spotlight.
Without further ado, we invite you to scroll down and see these brilliant shapeshifters for yourself. While you’re at it, make sure to check out the conversations we had with voice and accent coaches Ashley Howard, Holly Renaut, and Sarah Valentine, who kindly agreed to let us in on the secret of how accent masking works.
#1
Gary Oldman
In fact, he had to relearn his natural accent with a voice coach.
I’d award him extra points for being such a great chameleon overall. There have been times that I had no idea it was him in a particular role.

I’m always surprised. Idris Elba and Tom Holland come to mind.
Hearing Christian Bale in Ford vs Ferrari and me wondering what the f**k is this man doing with a cartoon Brit accent. Then looking it up and many people insisting that’s close to his real accent.

#5
I grew up with Hugh Jackman as Wolverine. I’d never heard him be anything else.
Imagine my reaction when I first heard his native Australian accent lol

Melanie Lynskey. I seriously couldn’t believe she was from New Zealand and went straight to YouTube to hear her original accent. She embodies her American characters so well, especially in I Don’t Feel at Home in This World Anymore

I knew she wasn’t American, but Kate Winslet’s Bucks county accent in the Mare of Eastttown was on point.

#14
Karen Gillan
She’s does a really good American accent. Even more impressive since she is Scottish

Heath Ledger in Lords of Dogtown had such an authentic Southern California surfer accent, like so specific and niche, that to this day I’m still surprised he was Australian. Rip.

Juno Temple from the new season of Fargo (who I believe is English with a cockney/estuary accent). Insanely good Midwestern accent without overdoing it.

Andrew Lincoln. Except it was the other way. Knew him from Love Actually. So seeing him in The Walking Dead was shocking.
Same with having grown up with Boondock Saints. My dumb self still somehow believed Darryl actor was actually Irish …. sigh

The guy that played Apollo in the Battlestar Galactica reboot – Jamie something I think – I don’t feel like googling his last name but the first time I watched an interview with him I didn’t hear a single word he said I was so flabbergasted at his accent and how well he hid it in the show. I’m surprised I’m haven’t seen him in more stuff, he was pretty good. Maybe he just doesn’t do the type of stuff I watch.
